Abstract:
A pixel circuit may include a detection circuit having first and second transistors coupled in series between differential output nodes of an antenna. The antenna may be configured to be sensitive to terahertz radiation. The pixel circuit may also include a capacitor coupled to an intermediate node between the first and second transistors, and control circuitry coupled to control nodes of the first and second transistors. The control circuitry may be configured for selectively applying to the control nodes a gate biasing voltage for biasing the control nodes of the first and second transistors during a detection phase of the pixel circuit, and/or a reset voltage for resetting a voltage stored by the capacitor.
