Abstract
Box switches are stacked sharing a common current from power sources. The power sources may be current, voltage or a combination of such sources. In preferred embodiments, the transistor switches in the box switches may be paralleled by different polarity transistors that will act to better balance and make symmetrical the output signals. Capacitors may be used to smooth out residual noise voltage signals.
