A MOSFET-only continuous-time 560 kHz tunable bandpass filter
A MOSFET-only filter is described which employs an amplifier-regulated cascode structure to realize both conductance and transconductance, while the required capacitors are realized by MOSFET gate capacitance. The filter configuration is such that both MOSFET capacitors and MOSFET resistors are always biased in the triode region, so that the only remaining nonlinearity is that caused by mobility degradation due to the normal field, which can be reduced by differential structures.
