Abstract
A second order bitstream /spl Sigma//spl Delta/ modulator, using compact switched current memory circuits (CMCs) have been implemented. The structure uses the commonly used integrator structure, and calculations predetermine -57-dB noise floor for a 20 kHz bandwidth and 1-MHz clock frequency. A chip is under fabrication.ETX
