An integrated detection circuit (10) linearly charges capacitors (14) and (16) over time in response to particular states of an input signal (12). Outputs from the integrated detection circuit (10) are generated by differential pairs (39) when the charge on either of the capacitors (14) or (16) is equal to or greater than a reference voltage input to the differential pairs (39).

Method and apparatus for detecting changes in a clock signal to static

A multi-mode digital to analog converter for converting a digital input into an analog voltage according to a linear or a companding transfer function. The converter comprises a charge redistribution device for creating an analog voltage at a node and switching circuitry for controlling the charge redistribution device. The switching circuitry is operable to effect either transfer function responsive to its inputs.
