ABSTRACT:
A CMOS circuit for steering current utilizing minimal power includes a first stage comprising a first powering transistor and a first idling transistor essentially in a parallel configuration and placed in series with a second stage comprising a second powering transistor and a second idling transistor also essentially in a parallel configuration. The circuit is configured to allow the first idling transistor to supply a substantially constant low level, idling current, and the first powering transistor to controllably supply a higher, powering current. The second stage serves to direct the electric current provided by the first stage. When powering current is not required, the circuit draws only the low idling current.
