Abstract

This paper presents a 3rd order switched current Sigma-Delta modulator. The Sigma-Delta modulator operates at a sampling rate of 600kHz and the signal band is 5.5kHz, i.e. an oversampling factor of 54.5 is used. Multiple input signals are used to reduce the internal signal swings which results in reduced power consumption. The shaping of the noise from the 2nd and 3rd integrator is used to allow the noise power from these integrators to be increased to further save power. The total power consumption is approximately 2.5mW with a supply voltage of 3.3V. The maximum SNR is approximately 74.5dB.
