ABSTRACT:
An amplification circuit comprises a detector (15) for detecting transmitted radio signals in the range 0.5 GHz to 20 GHz and a wideband logarithmic video amplifier (WLVA 16). The WLVA is fabricated on an application specific integrated circuit (17) for example with a temperature sensor (20). The output from the temperature sensor is supplied to a second ASIC (24) which samples the temperature signal and supplies compensation signals read from a non-volatile memory device.
