transconductance

[¦tranz·kən′dək·təns]
(electronics)
An electron-tube rating, equal to the change in plate current divided by the change in control-grid voltage that causes it, when the plate voltage and all other voltages are maintained constant. Also known as grid-anode transconductance; grid-plate transconductance; mutual conductance. Symbolized Gm ; gm .
A field-effect-transistor rating, equal to the change in drain current divided by the change in gate-to-source voltage that causes it, when the drain voltage and all other voltages are maintained constant. Symbolized gfs .
An amplifier parameter, equal to the change in output current divided by the change in input voltage that causes it. Symbolized gm .

The transconductances of VDTA were controlled by bias currents.
It has little impact on the source-drain voltage of tail transistors and the transconductances of the cross-coupled transistors, and so does the amplitude of the output signal.
Because MOS transistors need high bias currents to obtain good transconductances, this is the configuration selected to implement the oscillator, expecting a reduction in the power consumption for a same phase noise value, compared with other architectures.
Under small presence of parasitic resistances and transconductances, the dispersion relationship becomes complex: [k'.
25 [[micro]meter] channel CMOS devices with transconductances of 240 ms/mm for the nFET and 140 ms/mm for the pFET are currently under development.
Fixing this degree of freedom, we have to select correct positions in admittance matrix where specific transconductances ([g.
Both types of devices have very high transconductances, from a median value of 1270 to 1580 mS/mm.
The transconductances of the controlled sources are set to unity, and the coefficients of the nonlinear conductance are those of the nonlinear controlled source to be simulated.
Current Differencing Buffered Amplifier (CDBA) and Current Differencing Transconductance Amplifier (CDTA) use the differential input currents, whereas Voltage Differencing Transconductance Amplifier (VDTA), Voltage Differencing Current Conveyor (VDCC) and Voltage Differencing Buffered Amplifier (VDBA) employ differential input voltages [3]-[12].
