| Abstract: | A second order switched capacitor sigma-delta modulator operating at a supply voltage of 1V is presented. 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 been carried out in a fully differential configuration in order to minimize errors arising from charge injection and clock-feedthrough effects. The converter has been implemented using a conventional 0.8 pm double-poly double-metal CMOS process and test results, showing more than 9 bits of resolution with oversampling ratio of 64, are presented. |
