Abstract	A low power analog matched filter circuit with smart sliding correlation is proposed for direct sequence code division multiple access (DS-CDMA) despreading process. The influence of level shifter mismatch on the trade-off between speed, power and resolution of the analog correlator circuit is investigated with respect to technology scaling. The optimization in power, acquisition time and areal efficiency is considered. Simulation with code length of 127 reveals that the analog matched filter circuit provides good linearity, and dissipates only 22 mW at a voltage supply of 3.3 V and an operational clock frequency of 128 MHz, using 0.35 μm CMOS technology.
