Abstract: An FET RF signal detector circuit comprising two unbalanced differential transistor pair circuits is disclosed. A current mirror output circuit is included for generating an output current derived from currents flowing in the differential transistor pair circuits. The first unbalanced differential transistor pair circuit comprises two branches, each with a respective tail, and a first variable resistor between the branch tails. The first unbalanced differential transistor pair circuit connects to a first current source tail arrangement. The second unbalanced differential transistor pair circuit comprises two branches, each with a respective tail, and a second variable resistor between the branch tails. The second unbalanced differential transistor pair circuit connects to a second current source tail arrangement.
