摘要

This paper discusses the use of a transconductor, first proposednby Nauta for high frequency applications, in low frequency CMOS gmn-C bandpass filters. The behavior of the transconductor isnexamined in detail, showing that the robust implementation ofnhigher-order low-voltage filters is possible for center frequencies innthe lower megahertz region. The experimental results are presented ofnthe realization of two prototypes, a 0.6-Μm CMOS 18th-order realnbandpass filter and a 0.35-Μm CMOS 7th-order complex (14th-ordernbandpass) filter, both with a center frequency of 3 MHz and a passbandnof 1 MHz. These filters comply with the specifications for thenchannel-select stage of the Bluetooth short-range radio receiver
