Abstract: Self configuring output stages of precision amplifiers that remain linear when operating into a load that may have a ground reference below the amplifier ground reference, that maintain full amplifier gain while approaching zero output, and that can provide a zero output even when operating into a load that may have a ground reference below the amplifier ground reference, that has a self configuring output stage operable with either a mid-rail or ground reference below amplifier ground, and which maintain a high output impedance when not selected even when the output is above the amplifier supply voltage, or when not powered, thereby allowing amplifier outputs from un-powered amplifiers or amplifiers operating at lower supply voltages to be connected in common for multiplexing to a common load.

Abstract: Auto-gain correction in a precision amplifier provides continuous calibration of the gain of the two differential input stages relative to each other and thus significantly minimizes the effects of device mismatch and temperature. Auto-gain correction together with auto-zero minimizes the effects of common mode input voltage on the amplifier and eliminates the need for trim associated with the matching of the two differential input stages. Improved gain matching enhances the accuracy of the auto-zero, which further improves the accuracy of auto-gain correction, resulting in a synergy with both operating together. The implementation of the auto-zero using an input pair of series capacitors in conjunction with a common input reference and a feedback pair of series capacitors in conjunction with a common feedback reference provides for decoupling the common mode voltage of the input differential pair or feedback differential pair. Various features may be used in sub-combinations as desired.

Abstract: The invention is a means for ensuring full current flow in the "forward" direction in a MOS transistor, and substantially reducing (and/or eliminating) current flow in the "reverse" direction. The forward voltage drop and reverse current are controllable and are determined by ratios of device size. In one embodiment, the present invention is a circuit coupled to an output stage transistor having an output voltage thereon to ensure current flow in one direction and to throttle current flow in a reverse direction. The circuit includes a first circuit coupled to the output transistor to progressively turn off the same as the output voltage reaches a first threshold voltage and approaches a rail voltage. The circuit further includes a second circuit coupled to the output transistor to turn off the same as the output voltage reaches a second threshold voltage where the second threshold voltage is greater than the rail voltage.
