Abstract :
This paper describes the implementation of a low-voltage, wide bandwidth, continuous-time low-pass ΔΣ modulator. The presented modulator operates at a supply voltage of 1.8 V and can achieve a maximum SNDR of 74 dB (more than 12 bits) for an oversampling ratio of 32 and in a bandwidth of 2.5 MHz.
