Wideband RF detector design for high performance on-chip test

A wideband, high dynamic range RF amplitude detector design aimed at on-chip test is presented. Boosting gain and sub-ranging techniques are applied to the detection circuit to increase gain over the full range of input amplitudes without compromising the input impedance. Followed by a variable gain amplifier (VGA) and a 9-bit A/D converter the RF detector… CONTINUE READING
