摘要

An integrated RF tuner, operating in 40MHz- 900MHzbandwidth for cable modem is presented using TSMC0.35µm (four metal, double poly) process. RF tuners alwayshave external components which increases boardspace and cost. The complete monolithic RF tuner will bea cost, area and power efficient solution for DOCSIS standardhigh speed (10Mbps - 30Mbps) cable modems. Thedesigned RF tuner has an end to end gain of 0 dB, and adjacentchannel rejection of -34 dB without any external SAWfilters. The total area is 3m.m. x 3m.m. with a power consumptionof 680mW with a 3.3V supply.
