ABSTRACT:
A low offset field effect transistor correlator circuit where one signal is applied to a balanced input through capacitors to the drain and source electrodes of a field effect transistor and having a second signal applied to the gate of the transistor. Low pass filters are connected to the source and drain, and the correlated input signals appear across resistors connecting the outputs of the filters.
