Op amp offset compensation3/29/2024 The circuitry of claim 2 wherein said diodes for each said operational amplifier are series connected to the output terminal of that operational amplifier, with at least one of said diodes being forward biased and at least one of said diodes being backbiased.Ħ. The circuitry of claim 2 wherein said diodes for each said operational amplifier are series connected to the output terminal of that operational amplifier, with each said diode being backbiased.ĥ. The circuitry of claim 2 wherein said diodes for each said operational amplifier are series connected to the output terminal of that operational amplifier, with each said diode being forward biased.Ĥ. The circuitry of claim 1 wherein said current blocking means includes at least one diode through which the output of each said operational amplifier is applied, said diodes for each said operational amplifier presenting an accumulative diode voltage drop greater than the offset voltage output level of that operational amplifier.ģ. Means for blocking current flow from the output of each said operational amplifier unless the output voltage thereof exceeds the offset voltage output thereof when other than null output conditions exist at the inputs of that operational amplifier.Ģ. In circuitry of the type having at least one operational amplifier which generates an offset voltage output when null output conditions exist at the inputs thereof, the improvement comprising:
