Abstract
A third-order channel selection filter for multi-mode
direct-conversion receivers is presented. The filter is designed
with a Butterworth prototype and with the target wireless appli-
cations of Bluetooth, cdma2000, Wideband CDMA, and IEEE
802.11a/b/g/n wireless LANs. Linear-region MOS transistors
are used to perform voltage-to-current conversion. The wide
tuning range is achieved by the current multipliers and linear
voltage-to-current converters. Implemented in the TSMC 0.18
