High speed sample and hold circuit design
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Sampling of the time-varying input signal is the first step in any type of Analog to Digital (A/D) conversion. For Low Power and high-speed A/D converter, a high-performance Sample and Hold (S/H) circuit is needed as its ...
High-performance low-voltage current mirror design
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Design of high precision analog circuits requires accounting for the mismatch between nominally identical transistors. In this work, errors affecting CMOS current mirrors due to mismatch between identical transistors are ...
Radiation analysis of microstrip active (amplifier) and passive (antenna) structures
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Analysis of radiation from a microstrip amplifier and a newly proposed microstrip antenna is presented. Microstrip amplifier is analyzed replacing the MMIC structure by an equivalent S2P model and remaining portion being ...
