Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
The Myril B. Reed Best Paper Award is given each year for the best paper presented at the previous Midwest Symposium on Circuits and Systems. Myril B. Reed was instrumental in establishing MWSCAS and, along with Ray M. Wainwright, chaired the first two Midwest Symposiums, in 1955 (University of Illinois, Urbana) and 1956 (Michigan State University). The MWSCAS 2016 Myril B. Reed Best Paper Award is...
Linton Salmon joined DARPA as a program manager in September 2014. His research interests include semiconductor process and design technology and its application to defense systems. Prior to joining DARPA, Dr. Salmon spent 15 years in executive roles directing development of CMOS technology from the 130nm through the 7nm node at GlobalFoundries, Texas Instruments and Advanced Micro Devices. He focused...
This paper presents a CMOS image sensor with high conversion-gain pixels and column-shared pipelined ADCs for Fluorescence-lifetime imaging microscopy (FLIM). Pixel conversion gain of 121 uV/e-is achieved by creating a distal floating diffusion from transfer gate and reset transistor gate without any process modification. 32-channel 10-bit on-chip column-shared pipelined ADCs with sampling rate up...
Mobile communication and navigation devices have fueled the demand for low power implementations to enhance battery life. A critical aspect of reducing power in these devices is the efficiency of the process of converting power from the battery to the various loads in the system. This makes high-efficiency DC-DC switching power converters a natural candidate for such task. Unfortunately, however,...
The recent increase in RFID usage coupled with the evolving IoT has revamped the need for Wireless Power Transfer (WPT). In this paper, a brief review of systems using WPT is offered including: RFIDs, inductively coupled systems and electromagnetic harvesters. A case study for phased array antenna beamforming and its benefits to wireless power transfer are given. A 3x linear patch array at 5.8 GHz...
This paper introduces a multi-loop fast transient response flipped voltage follower (FVF) low-dropout (LDO) voltage regulator suitable for system-on-chip (SOC) applications. While typical FVF-based LDOs exhibit fast transient response, which is critical for SOC applications, their output DC accuracy is limited due to low loop gain of the FVF. In this work, we introduce a multi-loop design aimed at...
The 5G wireless revolution will bring some fundamental changes on the design of handsets and communication infrastructures, delivering over 10 Gbps download speed with unprecedented densely connected wireless devices. The 5G RF transmitters using phased-array MIMO (multiple-input and multiple-output) antennas will demand excellent power efficiency with high integration and linearity at the cm-Wave/mm-Wave...
The flipped voltage follower (FVF), a variant of the common-drain transistor amplifier, comprising local feedback, finds application in circuits such as voltage buffers, current mirrors, class AB amplifiers, frequency compensation circuits and low dropout voltage regulators (LDOs). One of the most important characteristics of the FVF, is its low output impedance. In this tutorial-flavored paper, we...
Digital MIMO receivers featuring digitization at each element are critical for (massive) MIMO applications since they support complex space-time signal processing. However, the lack of spatial selectivity in the analog/RF domain necessitates high-dynamic-range analog-to-digital converters (A/Ds) to accommodate the uneven spatial power distribution, limiting the scale of such MIMO systems. This paper...
We propose μLeech, a new embedded trusted platform module for next generation power scavenging devices. Such power scavenging devices are already widely deployed. For instance, the Square point-of-sale reader uses the microphone/speaker interface of a smartphone for communications and as power supply. While such devices are used as trusted devices in security critical applications in the wild, they...
A method that replaces the temporal partial differential operators ∂n/∂tn of a partial differential equation (PDE) with Laplace domain impedances sn is proposed for realizing analog circuits that solve the wave equation. A systolic array of analog circuit modules is employed to simulate electromagnetic wave propagation. Mathematical models and corresponding analog circuits are described for internal...
Today's microprocessors and Systems-on-Chip are thermally limited. Many, therefore, employ dynamic thermal management (DTM) to maximize performance under a reliability constraint. Accurate thermal monitoring is critical as temperature underestimation can hurt reliability by excessively aging devices and overestimation can hurt performance by unnecessarily throttling computing components. Placing temperature...
Fundamental physical constraints, such as noise and channel capacity, set an upper bound to theoretical performance of many systems. In this work we examine the limitations of high-speed data in modern digital wireless radio systems. Although physical constraints provide an ultimate limit, we show that signal-to-noise-plus-distortion-ratio (SNDR) and nonlinearity of modern CMOS and Bipolar technologies...
