    Abstract: An approach to time domain filtering uses a passive charge sharing approach to implement an infinite impulse response filter. Delayed samples of an input signal are stored as charges on capacitors of a first array of capacitors, and delayed samples of the output signal are stored as charges on capacitors of a second array of capacitors. Outputs are determined by passively coupling capacitors of the first and second arrays to one another, and determining the output according to a total charge on the coupled capacitors. In some examples, a gain is applied to the total charge prior to storing the output on the second array of capacitors. In some examples, a charge scaling circuit is applied to the charges stored on the arrays prior to coupling capacitors to form the output.

    Abstract: Some general aspects of the invention relate to a circuit and to a method for analog computation, for example, using switched capacitor integrated circuits. In some examples, a circuit includes a first group of capacitors and a second group of capacitors that may store charges during circuit operation. The first and/or the second group of capacitors may include multiple disjoint subsets of capacitors. An input circuit is provided for receiving a set of input signals and for inducing a charge on each of some or all capacitors in the first group of capacitors according to a corresponding input signal. Switches, for example, transistors controlled by a sequence of clock signals, are used to couple different sets of capacitors. Different configurations of the switches are used to form different sets of the capacitors among which charge can redistribute.

    Abstract: In one aspect, reduced power consumption and/or circuit area of a discrete time analog signal processing module is achieved in an approach that makes use of entirely, or largely, passive charge sharing circuitry, which may include configurable (e.g., after fabrication, at runtime) multiplicative scaling stages that do not require active devices in the signal path. In some examples, multiplicative coefficients are represented digitally, and are transformed to configure the reconfigurable circuitry to achieve a linear relationship between a desired coefficient and a degree of charge transfer. In some examples, multiple successive charge sharing phases are used to achieve a desired multiplicative effect that provides a large dynamic range of coefficients without requiring a commensurate range of sizes of capacitive elements. The scaling circuits can be combined to form configurable time domain or frequency domain filters.
