Current steering folding circuit

摘要

A current steering folding circuit is provided. The current steering folding circuit includes a load and at least one current source for drawing a current from the load. The current steering folding circuit also includes a first output signal terminal for providing a first output signal, and a second output signal terminal for providing a second output signal. A current steering section is also provided. The current steering section steers the current between the first output signal terminal and the second output signal terminal based on an input signal. The first output signal is substantially equal to the second output signal for N values of the input signal. Advantageously, the number of current sources does not exceed N.
