Abstract

An apparatus is provided which generates a reverse bandgap reference using capacitive bias, which is applied to a single n-well diode. The capacitive bias allows for determining the current density precisely by pure timing control. An apparatus is also described for sensing temperature in which a forward-bias diode voltage can be sampled with a capacitor, and large current ratios are possible (e.g., ratio N greater than 1000). Duty cycle of a digital output of the sensor is used to determine the temperature sensed by the sensor.
