An integrated binary correlator module

A correlator module using the pseudorandom comparison (PRC) algorithm has been designed and fabricated in a standard 8 /spl mu/m PMOS process. It demonstrates the validity of the principle and the feasibility of a low-cost integrated correlator or RMS meter based on it. The chip runs at a sampling rate of 500 kHz, dissipates 90 mW, and its size is 2.4 mm/SUP 2/ not including the delay element which is an external standard component.
