Abstract
A circuit portion has an analog voltage supply module, a clock and a digital control module clocked by the clock. A bias voltage is applied to an analog voltage supply module so that it supplies a voltage to a node. The voltage is sampled at the node, at a signal edge of the clock, to obtain a sampled voltage. The sampled voltage is stored, the bias voltage to the analog voltage supply module is disabled and the sampled voltage is supplied to the node. A refresh signal is subsequently generated in response to at least one refresh criterion being met; and in response to the digital control module receiving the refresh signal, a refresh sequence is initiated. The refresh sequence includes re-applying the bias voltage to the analog voltage supply module; re-sampling the voltage at the node at a signal edge of the clock; and storing the re-sampled voltage.
