Abstract :
A 25MHz low-power sign and magnitude (SAM) converter for processing bi-directional currents is proposed. It converts the lowest current of ±1μA in less than 40ns, and does not require any static bias currents. The circuit is designed using a 0.35μm CMOS process, and functionalities are confirmed by simulation results.
