2] dependera no solamente del valor de la figura de ruido y consumo de potencia minimos requeridos para el filtro, sino tambien del SFDR (Spurious Free Dynamic Range -- Rango Dinamico Libre de Espurias) en su banda de paso, el cual esta estrechamente relacionado con los niveles de distorsion armonica y de intermodulacion de cada transconductor .
La figura 5 corresponde a la topologia del transconductor utilizada para la sintesis del filtro con bajo consumo de potencia.

Up to now, there have been lots of methods proposed to enhance the linearity of the mixer due to the nonlinear of the transconductor stage.
The Gilbert cell mixer consists of a class-A transconductor stage, a current commutating stage, and a load stage.
Over the years, transconductor
conceptions have been improved and also novel modified types were developed.
This is usually implemented by injecting part of the input transconductor
bias current into the tail of the switching core [31-33].
Th] > 0) for large signals is a nonlinear transconductor
and can implement both F squaring and [F.
is implemented with the fully differential symmetrical OTA topology with inherent common mode feedback .
Toshiba has applied class-D VCO developed with advanced CMOS technology, which use transistors as switches (not as transconductors
, like conventional VCOs).
