1. A device, comprising:
a digital to analog conversion cell comprising:
a first circuit configured to generate a first signal, the first circuit being a bias circuit;
a second circuit coupled to the first circuit, the second circuit configured to generate a second signal, based on the first signal and an input bit, the second signal having a first edge positioned in response to the first signal, the second circuit being a driver circuit; and
a third circuit coupled to the second circuit, the third circuit configured to generate a third signal having a second edge, in response to the first edge of the second signal, an amplitude of the third signal corresponding to the input bit, the third circuit being current steering circuit, wherein the second circuit includes a fourth circuit configured to provide a first drive strength of the second circuit, according to the first signal, the second circuit configured to generate the first edge of the second signal according to the first drive strength.
