ABSTRACT:
A low-pass filter circuit is disposed on a monolithic integrated circuit. An operational amplifier receives a reference potential and drives three parallel stacked diode paths into a current supply. One of the stacked diode paths conducts the vast majority of the current allowing the transistors of the other two stacked diode paths to operate in a sub-threshold region and represent an extremely high resistance. The high resistances in combination with a low value capacitor realizes a low-pass filter on the monolithic integrated circuit.
