would also like to thank my committee members for their valuable feedbacks. When I first start my study in the lab ECE245, there were numerous people who helped me. They include Hardy Schmidtbauer who were always good mentors to me. In particular, I would like to thank José Silva for helping me with valuable CAD support and Robert Batten for testing. It had been the equal pleasure working with ...

{ Two designs of a fully diierential transconductance ampliier to be used in a rst stage of a pipelined 13-Bit A/D converter are developed and presented. A three stage ampliier achieves the lowest power design. The dynamic range speciication is met according to the expression for noise power indicated in the design speciication sheet. In this report, anyway, we show that such expression is inco...

This paper presents a low-actuation-voltage micro-electromechanical system (MEMS) capacitive shunt switch which has a very large bandwidth (4 GHz to 24 GHz). In this work, the isolation of MEMS switch is improved by adding two short high impedance transmission lines at the beginning and end of a coplanar waveguide (CPW). Simulating the switch demonstrates that a return loss (S11) is less than -...

The design of an ultra low voltage, low power high speed 8 channel Analog multiplexer in 180nm CMOS technology is presented. A modified transmission gate using a dynamic threshold voltage MOSFET (DTMOS) is employed in the design. The design is optimized with respect to critical requirements like short switching time, low power dissipation, good linearity and high dynamic range with an operating...

A solution to the stability of capacitor-less low-dropout regulators with a 4pF Miller capacitor in Multi-level current amplifier is proposed. With the Miller compensation, a more than 50°phase margin is guaranteed in full load. An extra fast transient circuit is adopted to reduce stable time and peak voltage. When the load changes from light to heavy, the peak voltage is 40mV and chip quiescen...

The objectives of this paper are to investigate and develop a device that will produce high voltage low power supply. Generation of high voltage low power supply can be determined by using Flyback converter as an optimum method which can improve the design of the device to make it smaller in size, simpler and cost effective. In this paper, the device circuits are simulated using PSPICE software...

This paper describes design techniques for multigigahertz digital bipolar circuits with supply voltages as low as 1.5 V. Examples include a 2/1 multiplexer operating at 1 Gb/s with 1.2 mW power dissipation, a D-1atch achieving a maximum speed of 2.2 GHz while dissipating 1.4 mW, two exclusive-OR gates with a delay less than 200 ps and power dissipation of 1.3 mW, and a bufferflevel shifter havi...
