Passive Switched Capacitor RF Front Ends for Spectrum Sensing in Cognitive Radios
International Journal of Antennas and Propagation, 2014 This paper explores passive switched capacitor based RF receiver front ends for spectrum sensing. Wideband spectrum sensors remain the most challenging block in the software defined radio hardware design. The use of passive switched capacitors provides a

Biquadratic transconductance switched-capacitor filters
, 1993 Switched-capacitor (SC) filters yield efficient implementations in integrated form. However, they employ op-amps, each of which must be designed for a given filter separately. Furthermore, SC filters are not tunable.
