A new analog correlator circuit for a direct sequence code division multiple access (DS-CDMA) demodulator is proposed. The circuit consists of only 13 switches, 4 capacitors and 2 level shifters. Simulation with a code length of 127 reveals that the proposed circuit dissipates 3.4 mW at 128 MHz. The proposed circuit had been implemented into a Si chip using a 0.6 μm CMOS process. The occupation area of 256 μm×245 μm is estimated to be 9 times smaller compared to other reported equivalent analog correlators.
