SUMMARY A compact and effective transmission envelope detector (TED), which can detect whether the absolute amplitude of an input differential signal is larger than a threshold or not, is proposed. The TED has been demonstrated to be applicable for received signal strength indicator circuit in wireless communication receivers or power management systems, and mode‐control circuit in bidirectional optical transceivers. Implemented in a 0.18 µm CMOS technology, the TED has a response time of 210 ps at 5 Gbps, occupies an active area of 0.05 mm 2 , and consumes 1 mA from 1.8 V supply.
