Abstract
A differential amplifier includes an input pair of transistors with a source-side resistor circuit, having a transistor biased in a triode region, and a current source. The resistor circuit in combination with a capacitance, causes source degeneration in the amplifier. The source side resistor circuit includes a first MOS transistor having a first channel terminal connected to the source of a first transistor in the differential pair, and a second channel terminal connected to the bulk terminal, and a second MOS transistor having a first channel terminal connected to the source of a second transistor in the differential pair, and a second channel terminal connected to the bulk terminal. A bias circuit biases the first MOS transistor and the second MOS transistor in a triode region. The resistance of the source-side resistor circuit and the gain of the transistors in the differential amplifier can track across process corners.
