A 1v Second Order Sigma-delta Modulator
A second order switched capacitor sigma-delta modulator operating at a supply voltage of 1 V is presented. This low supply voltage restricts the gate overdrive voltage available for switching transistors. The design relies on the elimination of critical switches by using a modified switched op amp for the integrator and novel switched half-supply and reference voltage generators. The design has...

متن کاملBehavioral Analysis of Second Order Sigma-Delta Modulator for Low frequency Applications
Switched capacitor (SC) based modulator is prone to various non-idealities; especially at the circuit designing stage where the integrator plays an important role and effects the overall performance of the sigma delta modulator. The non idealities take account of sampling jitter which includes the effect of switching circuitry, sampling noise. Opamp parameter include noise, finite dc gain, fini...
