A saturable-transformer digital amplifier with diode switching

Abstract

Synopsis: A digital amplifier of simple non-critical design incorporating a saturable voltage transformer is described. The clock is a 2-phase, sine-wave voltage source in the 100-kc range. In structure and mode of operation the amplifier stage is particularly suited for use with 2-level diode gating to provide the "and" and "or" logical functions. A complementer employing two saturable transformers provides the "not" function. The volt-second transfer characteristic of the stage critically determines the stability of transmission of binary signals in a long register, or in any closed loop. Factors governing the shape of this characteristic are discussed. The over-all characteristic for n stages is then derived and used to predict binary transmission stability.
