A 3.4mW 65nm CMOS 5th Order Programmable Active-RC Channel Select Filter for LTE Receivers
Författare
Summary, in English
active-RC low pass filter that meets Rel-8 LTE receiver
requirements has been designed with programmable bandwidth
and overshoot. Designed for a homodyne LTE receiver,
filter bandwidths from 700kHz to 10MHz are supported.
The bandwidth of the operational amplifiers is improved
using a novel phase enhancement technique. The filter was
implemented in 65nm CMOS technology with a core area
of 0.29mm2. Its total current consumption is 2.83mA from a
1.2V supply. The measured input referred noise is 39nV/
√
Hz,
the in-band IIP3 is 21.5dBm, at the band-edge the IIP3
is 20.7dBm, the out-of-band IIP3 is 20.6dBm, and the
compression point is 0dBm.
