Abstract
Disclosed is a multistage resistor and transistor network for use in forming a plurality of weighted signals and which utilizes a conventional R-2R ladder network connected to a single reference means for decrementing the reference signal into weighted signals and a remainder signal. Rather than terminating the remainder, as in the prior art, at least one slave ladder network is connected for receiving the remainder signal and decrementing the remainder signal into a plurality of decrementally weighted signals to be taken in parallel with the decrementally weighted signal segments of a master ladder.
