This paper presents the design and analysis of a high-gain, low-power, two-stage CMOS operational amplifier (op-amp) for a sigma-delta ADC. Op-amp topologies, such as folded cascade, telescopic and two-stage, are discussed in this paper. The theoretical and topological analyses of each design are highlighted in detail, including the tradeoff among various(More)
The design of a cascode Pierce oscillator circuit with separation supply for a MEMS surface acoustic wave resonator is proposed. The cascode Pierce topology provides sufficient gain to counteract the high insertion losses of -65dB at 1.3GHz of the SAW resonator. This circuit was designed using Silterra's 0.13um CMOS process and has low power consumption of(More)
