Methods and circuits for enabling slew rate programmability and compensation of input/output circuits

Abstract

Various embodiments of circuits and methods for enabling a slew rate programmability and compensation of input/output circuits are provided. The circuit includes a delay code generation circuit and at least one input/output (I/O) circuit. The delay code generation circuit is configured to receive a clock signal and a delay factor and generate a compensated delay code based on the clock signal or a combination of the delay factor and the clock signal. The I/O circuit includes a plurality of delay lines associated, integrated or communicatively associated with the delay code generation circuit and is configured to program the plurality of delay lines so as to generate a predetermined delay corresponding to the compensated delay code in order to achieve a predetermined slew rate of the I/O circuit.
