Abstract
A circuit includes an input transistor pair with first and second input transistors, the first input transistor having a control terminal configured to receive an input signal and a cascode transistor pair including a first and second cascode transistors having a common control node. A bias circuit has a bias input configured to receive the input signal and a first bias output coupled to the common node of the first and second cascode transistors. The bias circuit includes a signal tracking circuit operating to generate the first bias output to track the input signal. A pair of load transistors are coupled to the input transistor pair and biased by a second bias output of the bias circuit.
