Abstract :
A general method for the construction of highly-linear CMOS differential transconductor cells (DTCs) is presented. Basic assumptions which allow several tunable CMOS transconductance cells to be formed are discussed. The method is based on the simplified square-law relationship of the MOSFET transistor. Extensive SPICE simulation results with MOSFET parameters as realistic as possible confirm the theory.
