... The design is derived from a circuit published in the October 1999 issue of the magazine Elektuur. After building the circuit it just worked ! The circuit was built using the "dead bug" method (so not etched PCBs). As told, the frequency range stretches from appr. 4.5 till 11 MHz; the on-board oscil ...

... A high-performance ultrahigh-frequency amplitude shift keying (ASK) detector for lowpower radio-frequency (RF) receivers is proposed. The circuit is based on a high-gain common-source topology with a feedback loop that provides adaptive biasing. Hence, high sensitivity and rail-to-rail input operati ...
