Abstract
An amplifier includes a dynamic bias circuit and an amplification circuit coupled to the dynamic bias circuit. The dynamic bias circuit includes a plurality of transistors coupled to a plurality of resistors. The dynamic bias circuit is configured to generate a bias current with a magnitude that increases in response to the dynamic bias circuit receiving a falling edge of an input signal and decreases in response to the dynamic bias circuit receiving a rising edge of the input signal. The amplification circuit is configured to receive the bias current and amplify the input signal based on the bias current to generate an output signal that has a higher slew rate for a falling signal than for a rising signal.
