摘 要: | A high-performance low-powerΣΔanalog-to-digital converter(ADC) for digital audio applications is described.It consists of a 2-1 cascadedΣΔmodulator and a decimation filter.Various design optimizations are implemented in the system design,circuit implementation and layout design,including a high-overload-level coefficient-optimized modulator architecture,a power-efficient class A/AB operational transconductance amplifier,as well as a multi-stage decimation filter conserving area and power consumption.The ...
