proposed a 60-GHz transconductor consisting of a CS transistor whose DC current is shared by other two transistors [60].
At node (a) of Figure 2, for a positive half cycle of LO signal, [M.sub.3] is switched off while [M.sub.1] is switched on, resulting in the transconductor to be switched on.
The model is formed by the parallel connection of an LC tank, whose losses are represented by an equivalent resistance R, a nonlinear two-terminal transconductor described by the current-voltage relationship [i.sub.nl](v), and a controlled current source described by the current-voltage relationship [i.sub.in](v, [v.sub.in]), where v denotes the differential voltage between the drain nodes of the ILFD.
