This paper presents the analysis and design of high speed, high gain fully differential operational amplifier(op-amp). The op-amp is designed for sample and hold circuit of 14 bit 100 MS/s pipelined analog-to-digital converter (ADC). Both the main op-amp and the boosting op-amp are fully differential folded-cascode. The main op-amp has a switched capacitance common mode feedback circuit. The boosting...
Clocked comparators have found widespread use in noise sensitive applications such as wireline receivers, A/D converters, and memory bit-line detectors. However, their nonlinear, time-varying behavior and discrete output levels have discouraged the use of traditional small-signal noise simulation techniques such as NOISE in SPICE. This paper asserts that the periodic noise analysis available from...
This paper describes a comparative analysis between two topologies of operational amplifiers to design a 40 MS/s 12-bit pipeline analog to digital converter (ADC). The analysis includes AC and transient simulation to select the proper topology. This ADC is implemented in a 0.35 mum AMS CMOS technology with 3.3 V single power supply. The capacitors and selected operational amplifiers were scaled for...
