Abstract:
1. An apparatus, comprising: a transmitter circuit that includes a first branch and a second branch, the transmitter circuit to receive an input binary signal in a signed form including a polarity bit to represent a sign of a value of the input binary signal; wherein the first branch is activated to send an output analog signal while the second branch is inactivated, and wherein the second branch is activated to send the output analog signal while the first branch is inactivated; and wherein selection of the first branch or the second branch to activate to send the output analog signal is based on the polarity bit of the input binary signal received by the transmitter circuit, wherein the polarity bit of the input binary signal is a most significant bit of the input binary signal that controls a sign of an output voltage of the transmitter circuit, and wherein remaining bits of the input binary signal control an absolute value of the output voltage.
