Robust super-regenerative receiver with low susceptibility on clock jitter employing synchronous peak-held envelope detector

A robust 400 MHz super-regenerative receiver with low susceptibility to clock jitter is proposed. The conventional un-clocked envelope detector (ED) is replaced with a synchronous peak-held ED, where its peak detection value is kept during oscillator quenching OFF time by switching off the charging path of ED, synchronously with quenching clock. In this way, the flattened peak level not only allow...
