Abstract
A circuit for inductive peaking may include a driver, an inverter, a resistor between an output node of the driver and an input node of the inverter and a switch. For example, a first node of the resistor may be connected to the output node of the driver and a second node of the resistor may be connected to the input node of the inverter. The switch may be connected between an output node of the inverter and the first node of the resistor. An input node of the driver may correspond to an input node of the circuit and the output node of the driver may correspond to an output node of the circuit.
