Abstract: An Operational Analog to Digital (SYMAD) Convertor cell for converting an analog signal into a discrete binary code. An analog signal is processed by sample and hold circuitry and then compared to a reference voltage by a comparator. The comparator output is the converted digital output. This output is coupled back to the control input of an analog switch which selects either the reference voltage or a predetermined potential, typically zero volts, to couple to an inverting input of an operational amplifier. The analog signal input is also coupled to the non-inverting input of the operational amplifier. The operational amplifier is configured as a differential amplifier with a gain of two. If the digital output of the comparator is a logic 1, then the operational amplifier output is two times the difference between the analog signal and the reference voltage. If the digital output of the comparator is a logic 0, then the output of the operational amplifier is two times the analog signal.

Abstract: An n-bit analog processing circuit constructed with network swappers has n stages and an input port for inputting an analog signal to be processed. Each of the n stages includes first and second reference input ports, at least one swappable network having first and second terminals, and a switching element that is responsive to a digital input signal for varying a connectivity of the first and second terminals with respect to the first and second reference input ports. Each of the n networks has a primary electrical characteristic that is binarily weighted with respect to others of the networks. The primary electrical characteristic may be resistance, capacitance, capacitive reactance, inductance, inductive reactance, voltage potential, gain, transconductance, superconductance, time delay, permeability, electrical or optical conductor length, and/or winding turns.
