Abstract
A dual-mode Bluetooth/ZigBee low-IF polyphase
channel ¯lter has been designed with 0.18 ¹m dig-
ital CMOS technology based upon transconductor-
capacitor (GmC) structure. The ¯lter has a ¯fth-
order 0.5dB equiripple Chebyshev bandpass response.
It achieves a signal-to-noise ratio of 62dB and in-
put referred third-order intermodulation intercept of
33dBVp (for distant blocker interference). The ¯lter
consumes a moderate power of 2.5mW from a 1.8-V
single supply in both modes of operation. |
