摘要： A time-to-digital converter (TDC) uses voltage as a representation of time offset. A voltage change is induced over a time period from a start signal to a stop signal. The final voltage is then measured, and the voltage measurement is mapped to a time value representing the time between the start signal and the stop signal. The voltage change can be increasing or decreasing, e.g., by charging or discharging a capacitive circuit between the start signal and the stop signal. The voltage can be measured using an analog-to-digital converter (ADC) or other voltage measurement circuit. The voltage measurement can be mapped to the time value in any manner, such as, for example, using a transfer function or using a mapping table that provides a time value for each possible voltage measurement value.

摘要： An improved system and method for reducing the ambient noise experienced by a user listening to an earpiece without the use of a microphone is disclosed. An “ambient noise signal” created by the sound pressure wave of the ambient noise acting on the earpiece transducer is obtained. In some embodiments, the ambient noise signal is inverted and fed back, and the inverted signal is added to the intended audio signal being sent to the earpiece so that the ambient noise is cancelled. In other embodiments, a processor receives the ambient noise signal and predicts the modification to the intended audio signal needed to counteract the ambient noise. The ambient noise signal may be obtained by comparing the actual signal across the earpiece transducer to the intended audio signal, or by detecting variations in the current across the transducer from the current generated to drive the transducer.

摘要： An on-chip DC voltage generator and hardware efficient method provide for generating linear DC voltages with a programmable negative temperature coefficient. A temperature-dependent DC voltage is digitally derived from an on-chip temperature readout, a programmable digital word to control the temperature coefficient and a programmable digital word to adjust the digital level. The digital result is applied to a resistor string digital to analog converter (DAC) to generate an analog DC voltage with a negative temperature slope. Additionally, another programmable digital word for trimming allows convergence at a given temperature of voltages having a common level but different temperature coefficients. These voltages can be applied to the word line in the flash memory and track the threshold voltage of the memory cell, which has a negative temperature coefficient, such that the difference between the gate voltage and the threshold voltage is constant over temperature.

摘要： In the power supply apparatus which performs voltage conversion of an input voltage (Vbat), with a predetermined set voltage as a target value, and outputs the converted voltage, a boost ratio setting unit sets a boost ratio (XCP) of the charge pump circuit based on the input voltage (Vbat) and a predetermined set voltage. A voltage adjustment unit is a regulator circuit, and adjusts voltage (Vx) so that output voltage (Vout) of the charge pump circuit approaches the set voltage. An output voltage setting unit generates a predetermined set voltage as a digital value (Dset). An A/D converter performs analog-digital conversion of the input voltage (Vbat). The boost ratio setting unit sets the boost ratio based on a result of comparing an input voltage (Ddet) that has undergone analog-digital conversion, and the set voltage (Dset).
