    • Analog-to-digital (A/D) and digital-to-analog (D/A) converter circuits are provided using charge redistribution. The analog-to-digital converter circuit also employs successive approximation binary search techniques wherein the number of search voltages generated is a minimum. The analog-to-digital circuit includes a digital-to-analog converter circuit, a comparator circuit and a logic control means. The digital-to-analog circuit, under control of the logic means, accepts a reference voltage input and produces a sequence of search voltages which are compared with an unknown analog input voltage at the comparator. The resultant outputs from the comparator are applied to the control logic to determine the search voltage sequence. The digital-to-analog converter for the aforesaid circuit is provided in one embodiment employing charge-coupled-device technology. A substrate and two storage electrodes are combined to produce two potential storage wells and a transfer electrode is provided to move charge carriers between the storage wells. A reference charge packet Q.sub.R is stored and divided by charge redistribution between the two potential wells to produce a sequence of charge packets of value Q.sub.R /2, Q.sub.R /4, Q.sub.R /8, Q.sub.R /16 etc. which can be selectively combined to produce analog output of a D/A converter. In the A/D converter the same sequence of charge packets is used to generate the equivalent of a binary search sequence Q.sub.R /2, Q.sub.R /2.+-.Q.sub.R /4, Q.sub.R /2.+-.Q.sub.R /4.+-.Q.sub.R /8 etc. In another embodiment a bucket brigade device is provided to accomplish the same result. Because of the technique of charge redistribution wherein precise amounts of charge can be shifted in either direction between storage means, the total number of search value steps is a minimum.

    • A digital-to-analog conversion (DAC) circuit and trigger comparator combination is described for encoding and decoding charge packets in a common-well multi-level signal charge-coupled memory device (CCD). The DAC circuit, which may be of the weighted capacitor type, is used to generate a staircase waveform and to create the common-well under a first gate in the CCD. The trigger comparator adjacent to a second gate in the CCD is a detection circuit which stays in one binary state until an input charge signal is received, whereupon it switches state. In particular, the weighted capacitor DAC contains an extra offset bit which is used in the analog-to-digital or regeneration operation such that when the trigger comparator switches state, the digital input to the DAC at that time correctly represents the signal charge being converted. In one embodiment a circular serial-parallel-serial memory structure is employed as the multi-level CCD memory system.

    • A bucket brigade circuit is described for generating a sequence of packets of charge carriers of the form Q.sub.R /2, Q.sub.R /4, Q.sub.R /8....Q.sub.R /2.sup.N where N is an integer. The charge packets thus generated can be employed in combinations in either digital-to-analog or analog-to-digital converters. The charge generation circuit requires two equal capacitors which are used for charge redistribution. To obtain accurate quantities of charge in the generated charge packets the capacitors employed should be large, however the use of large capacitors results in low operating speed because of the large charge transfer time constants involved. The described circuit provides a scheme to reduce charge transfer time constants and therefore obtain greater speed while still permitting the use of large capacitors for high accuracy. The circuit includes a small coupling capacitor connected in series with one of the charge redistribution capacitors to produce a total capacitance which is equal to or smaller than the coupling capacitance. The sequence of charge carriers produced by the circuit can be injected into either a bucket brigade circuit or a charge-coupled-device circuit for use, for example, in digital-to-analog and analog-to-digital converters.
