Patent ID: 7012468

Claim:
A circuit configuration for reducing 1/f noise of at least one MOSFET in an electronic circuit, comprising: a voltage source for supplying a voltage to be amplified to a gate electrode of the at least one MOSFET; at least one DC current or DC voltage source connected to the MOSFET, said at least one DC current or DC voltage source delivering a DC current or a DC voltage for setting a constant operating point of the at least one MOSFET; a periodically oscillating current or voltage source connected to the at least one MOSFET, said periodically oscillating current or voltage source generating an alternating current overlaying said DC current or an alternating voltage overlaying said DC voltage for causing a periodic oscillation of the operating point about the constant operating point prescribed by said DC current or voltage source, such that defect states in an oxide of the MOSFET that are subjected to charge reversal under a condition of the constant operating point according to the laws of statistics and a 1/f noise signal, are no longer subjected to charge reversal statistically, but rather are subjected to a predefined charge reversal based on a modulation frequency of said alternating current or said alternating voltage.
