FM based pipeline ADC
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
This thesis aims at designing a new architecture for an FM based pipelined Analog to Digital Converter (ADC). It is based on the fact that power is a function of voltage and therefore handling with voltage becomes a difficult ...
Extremely low voltage operational amplifier design with rail-to-rail input common mode range
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Increasing trends towards battery operated systems demand circuits to be designed at low voltages. Low voltage operation severely limits the operational amplifier as a voltage buffer as the input common mode range available ...
Implementation of constant gm CMOS op-amp input stage using overlapping of transition region at 0.18 um technology
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Operational amplifier is the backbone of most of analog circuit design. For low voltage applications, op-amp should have a rail-to-rail common mode input voltage. This report describes the implementation of a constant gm ...
