Abstract :
In this paper, a low-voltage two pseudo-floating gate transistor all-pass filter is presented. The filter has adjustable phase-shift and only one filter capacitor. The filter operates at a supply voltage below 1 V and may have a power consumption below 160 nW. Simulation results for variable phase-shifts using Bsim3v3 are presented. The cut-off frequency or phase-shift of the filter is highly tunable.
