Patent abstract
An IC includes a device-under-test (DUT) configured to receive a first AC signal at a first node and output a second AC signal at a second node, the second AC signal being based on the first AC signal, and first and second detection circuits. Each of the first and second detection circuits includes a first gain stage coupled to a corresponding one of the first or second nodes through a first capacitive device, a second gain stage in a cascade arrangement with the first gain stage, and a low-pass filter configured to generate a DC signal based on an output signal of the second gain stage.
