Abstract
This article presents a low power, linear RF
front-end (RF-FE) for an 802.15.4a/z compatible impulse-radio
ultrawideband (IR-UWB) receiver. A complementary topology-
based LNA is proposed with a bandpass filter (BPF) integrated
into its output. The LNA includes a complementary common
gate (CCG) stage to isolate the BPF from the undesired loading
of the LNA’s input stage to achieve a high Q and 5- to
10-GHz tuning range. This CCG stage relaxes a trade-off
between headroom and linearity. Furthermo
