The ability to perform real-time signal analysis on physiological signal is important in today's technology. This allows physician to monitor their patient's health condition and provide the necessary action immediately. To obtain accurate measurement of this signal, proper signal interface between the patient body and the signal analyzer is crucial. In this work, a microprocessor system interfaced...
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 parameters such as gain, noise, output swings...
