ABSTRACT:
A waveform synthesizer for generating analog waveforms is provided utilizing all MOSFET integrated circuit logic. The synthesizer includes an n stage clocked shift register in which the input to the first shift register stage is the inverted output of the last shift register stage. The output of each stage controls the state of a preselected weighting unit field effect transistor which provides a preselected output whenever the corresponding shift register stage is a logic 1. The outputs of all the weighting unit transistors are summed and applied to a summing field effect transistor.
