Abstract
A linear tunable transconductor is designed with the use of linear COM posite n-channel MOSFETs (COMFETs) and CMOS COMposite FETs as basic ce lls. With crosscoupling, a differential linear relation is achieved wi th a THD at 1 kHz of 0.776% for a differential voltage of +/- 4V. The design of the transconductor demonstrates that COMFET devices can be s uccessfully used as standard cells in modulator analogue VLSI circuits . The transconductor performance at subthreshold is also discussed.
