A low-pass filter with automatic frequency tuning for a bluetooth receiver
(IEEE (Institute of Electrical and Electronics Engineers), 2011)
A third-order Gm-C Chebyshev low-pass filter with high linearity and automatic frequency programmability has been designed. The filter is intended to be used as a channel-select filter for a zero-IF Bluetooth receiver. The ...

Low-voltage tunable pseudo-differential transconductor with high linearity
(2009)
A novel tunable transconductor is presented. Input transistors operate in the triode region to achieve programmable voltage-to-current conversion. These transistors are kept in the triode region by a novel negative ...
