Abstract

The circuit has a capacitor (15) parallely connected with a resistor (14). An N-type FET (13) comprises a source connected to a voltage output (VIBATTERY) of the circuit, and a drain connected to another resistor (10). A differential output differential voltage amplifier (11) is cascaded with a mass referenced output differential voltage amplifier (12). The mass referenced output differential voltage amplifier has an output connected to a grid of the N-type FET or to another grid of a P-type FET (16).
