Abstract
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.
