Abstract: Representative implementations of devices and techniques provide analog to digital conversion of time-discrete analog inputs. A redundant binary scaled capacitance arrangement using a successive approximation technique can provide a fast and power efficient ADC, with improved error correction. For example, a successive approximation capacitor arrangement may include multiple arrays of capacitances with binary bit weights. In an implementation, the technique includes processing the capacitances in successive cycles, where each cycle generates a binary error correction code representing greater than one bit of the digital output.

Abstract: Some embodiments disclosed herein relate to techniques for providing a relatively constant oscillation frequency. In some instances, these techniques can make use of a ring oscillator that is powered by an adaptive voltage supply. The adaptive voltage supply provides a temperature-dependent supply voltage to respective delay elements in the ring oscillator, such that the oscillation frequency of the ring oscillator is approximately constant over a predetermined temperature range. For example, if temperature increases, the supply voltage can be increased proportionally, thereby tending to limit variation in the oscillation frequency delivered by the ring oscillator.
