An analog-to-digital conversion devices and methods that approach a linear relationship between resolution and oversampling rate. The process involves modulating an input analog signals with an essentially chaotic encoding signal that is deterministic, aperiodic in that it lacks spectral tones above a threshold, and bounded. The resulting encoded signal is quantized into a bit stream and decoded by applying to that bit stream a non-linear estimation related to said chaotic signal to thereby produce an output representing said input analog signal in digital form.

Transit-time based ultrasonic flow meter with analog-to-digital conversion for measuring ultrasonic signals, wherein accuracy of measurements is improved by making several measurements with different input offset, reference voltage, frame offset or sample rate in an analog-to-digital conversion stage.

Analog-to-digital converter (ADC) circuitry to convert an analog signal to a digital signal is disclosed herein. The ADC circuitry can utilize pipelined-interpolation analog-to-digital converters (PIADCs) with adaptation circuitry to correct regenerative amplification cells of the PIADCs. The PIADCs can implement a rotational shuffling scheme for correction of the regenerative amplification cells, where the correction implemented by the regenerative amplification cells allows for offsetting of latches of the regenerative amplification cells.

A radio frequency system. In some embodiments, the system includes a one-bit receiver, and the one-bit receiver includes a digital pseudo random noise generator, a one-bit digital to analog converter, a power combiner, a one-bit analog to digital converter, and a digital subtraction circuit. The digital pseudo random noise generator produces a signal added to the received signal before analog to digital conversion. After analog to digital conversion, a delayed version of the dither is subtracted from the digital signal.

An analog-to-digital converter is provided. The analog-to-digital converter is configured to convert an analog signal to a digital signal. The analog-to-digital converter includes a comparison circuit and a processing circuit. The comparison circuit is configured to compare the analog signal with each of a ramp signal and the ramp signal plus a predetermined offset to generate a control signal. The processing circuit, coupled to the comparison circuit, is configured to selectively store a count value of a counter circuit as the digital signal according to the control signal. When the control signal indicates that a signal level of the analog signal is greater than a signal level of the ramp signal and less than the signal level of the ramp signal plus the predetermined offset, the processing circuit is configured to store the count value as the digital signal.
