摘要： A power detector for detecting the RMS power of an AC voltage includes a transconductor configured to receive the AC voltage and to provide a first current to a node with a non-linear relation between the first current and the voltage. A current output digital to analog converter is configured to receive a digital signal and to provide a second current to the node. A low pass filter is coupled to the node, and an inverter is coupled to the node and configured to provide a binary signal.
