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 ...
Low power high slew-rate adaptive biasing circuit for CMOS amplifiers
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Adaptive biasing technique in analog and mixed signal integrated circuit design is used mainly to reduce the power and improve the driving capability. It has found many applications, like power amplifiers in RF communication ...
CMOS latched comparator design for analog to digital converters
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Conventional comparators are at the two extremes as far as power delay product and isolation between input and output is concern. Either they achieved very good isolation at the cost of power in the preamplifier or save ...
CMOS RFIC mixer design
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
A CMOS RF (Radio Frequency) up/down conversion mixer results in a reasonable increase in transceiver integration and a reduction in cost. The design of mixers faces many compromises between conversion gain(GC), local ...
Design of a low power high slew rate OPAMP and to study its impact on sigma delta modulator's performance
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
This thesis presents the work done on the design of a low-power, high slew rate opamp and subsequently the design of a fully-differential second order Switched-Capacitor architecture of a Sigma Delta modulator in 1.8 V, ...
Receiver amplifier design using CMOS current feedback amplifier and current conveyors
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
In the world of high-speed communications, systems involving high-speed data transfer require circuits with innovative features for good performance in terms of speed and power consumption. These data transfer systems ...
