The present work proposes a self-bias compensation technique for the frequency supply voltage dependence in low cost charge/discharge oscillator topologies. The main bias current of the oscillator will include a supply voltage dependent current. The main goal is to reduce the supply voltage dependence for a range between 1.6 and 2V, for a current starved ring oscillator and a new charge/discharge...
MOSFETs are modern devices used for electronic amplifiers. The MOS transconductance or shortly slope is a very important design parameter because it is directly linked with the magnitude of the amplifier voltage gain. Reducing the electronic devices dimensions in actual technologies creates strong advantages such as higher working frequency, but scaling down the structures has some drawbacks regarding...
Power MOSFETs are modern devices used for electronic switches. They have replaced classical bipolar power junction transistors that were until recently the main choice in power electronics applications. So, a new need for accurate MOSFET switches model in circuit simulators becomes important. The modern models, also called behavioral models, combine device behavior and circuit analysis in one single...
Power MOSFETs are electronic devices used for modern switches. The complexity of mixed-signal system-on-chip using power MOSFETs has increased. Advanced analog and digital interfaces, tough requirements for their safety and reliability impose new advanced methodologies for their simulations. Cadence Virtuoso offers a complex simulation environment including AMS, a mixed digital - analog simulation...
The piezoelectric materials used in the device industry with a very high market share are piezoceramics. They are used in medicine, robotics, mechanics but not least and the image stabilization. This material is easy to handle and with good properties related to mechanical and electric response. In full development are micro-electro-mechanical systems (MEMS) that bring with them new features, but...
This paper presents a new electronic system using an ATmega328P microcontroller, two ultrasonic sensors and two vibrating motors as a new helping solution for blind people navigation. The block diagram, specific requirements and implementations are described in the paper. Specific design problems and experimental adjustments are mentioned. Future optimizations and developing trends are also considered.
This paper presents an alternative solution to cooling applications by means of the Peltier effect, advantageous because there are no moving parts or fluids, leading to safer, reliable, and eco-friendly operation. Driven by DC power, our efficient system uses a Buck converter with custom designed blocks to ensure high performance.
In this paper we present a unity-gain follower amplifier based on a gated diode operated in breakdown regime in common cathode configuration. The amplifier has only one stage and it provides power amplification, high input impedance and a low output one. The maximum frequency that can be applied on the entrance of the amplifier so that the output remains undistorted is dependent on the bias current...
