A new circuit technique, the reconfigurable puise generator circuit is proposed to produce a puise width inversely proportional to the spectrum power bandwidth in the Impulse Radio Ultra-Wide Band (IR-UWB) circuits. The complete circuit was based on two pulse generator blocks using Positive Pulse Generator (PPG), and Negative Pulse Generator (NPG) to compose a rectangular waveform at the output. These...
This paper presents a simple equivalent electrical circuit model to represent spiral and cross inductors on CMOS Technology. The inductors were designed and simulated using Momentum/ADS from Keysight, and were fabricated on AMS 0.35 µm CMOS technology. Simulation data was used to develop a RLC model for the inductors, where the reactive elements are constant and the resistance depends on frequency...
This paper presents a fully integrated BPSK (Binary Phase Shift Keying) Transmitter Front End for Ultra-Wideband (UWB) applications, designed in 130 nm CMOS technology. A simple architecture based on parallel pulse generator blocks in parallel is proposed to produce 9th derivative Gaussian pulses. In addition to the pulse generator, the circuit comprises a passive balun circuit, a common source amplifier,...
This paper presents a novel compact pulse generator circuit for applications in IR-UWB systems designed in 130nm CMOS technology. A 10th order derivative Gaussian pulse is generated using charge pump circuits, which consists of a combination of positive and negative edge blocks.

In this paper, a new design for an impulse radar Ultra-wideband (UWB) module transmitter using a 180 nm CMOS TSMC process is presented. A 2nd order derivative Gaussian pulse is generated using two phase detectors, which consist of an n-latch and a p-latch to generate a single UWB pulse without any filtering and matches the FCC mask. The Gaussian impulse achieves a very small pulse of 259 ps width,...
In this paper, a new design for an Impulse Radar UWB transmitter using an 180nm CMOS process is presented. A 2nd order derivative Gaussian pulse is generated using two Phase Detectors (PDs), which consist of an n-latch and a p-latch to generate a single UWB pulse without any filtering and matches the FCC mask.

This paper presents a CMOS pixel motion detector based on a current-mode APS (Active Pixel Sensor) topology with wireless capability using an Impulse Radio - Ultra Wide Band (IR-UWB) in standard 0.35µm CMOS technology for applications in image sensor networks. A pixel was designed with a transmission gate to control one copier cell in order to compare different integration times. The pixel output...
This paper presents a fully integrated low-power 7th derivative Gaussian pulse generator for UWB applications designed in 180nm CMOS technology. We propose a simple architecture based on parallel pulse generator blocks that produce Gaussian pulses, and a pulse shaping stage which adjusts each pulse amplitude individually. The whole circuit has been simulated and the results have demonstrated the circuit...
This paper presents a design of an UWB PPM — Pulse Position Modulation transmitter based on a 1.8V, 0.18μm CMOS technology. We propose a pulse generator using modified Nand gate as a Phase Detector (PD) with an effective phase difference of 73ps. At the PD output an extra derivative circuitry exists. The whole circuit has been simulated using LTSpice and the results had demonstrated the circuit capability...
