Open the CIPO recordAbstract From the Canadian patent
A full-wave rectifier circuit useful in a low level envelope type video detector or the like comprises a symmetrical network having a pair of input terminals and an output terminal, the output terminal developing a unidirectional flow of current in response to the application of an alternating current signal to at least one of the input terminals. The symmetrical network comprises first and second cross-coupled transistors-current mirror pairs, each transistor being operable for conducting output unidirectional current through its respective current mirror. The current mirrors are connected for responding to the alternating current developed at the input terminals for operating one or the …
