Abstract :
A high-dynamic range RF RMS detector with 1 GHz bandwidth based on the dynamic translinear principle and integrated in a BiCMOS process is presented. The main computation is carried out in the current domain and errors due to finite transistor gain are compensated in the structure. To make the circuit suitable for voltage processing, both input and output interface circuits are included. Measurements on a prototype chip demonstrate the practicality of the circuit for an on-chip embedded tests.
