transconductance Electronics.|trɑːnskənˈdʌktəns, træns-, -nz-|
[f. transfer n. + conductance.]
The ratio of the (change in) current at one electrode or terminal of an active device, esp. the output, to the (change in) voltage at another, esp. the input; spec. = mutual conductance s.v. mutual a. 1 f.
1933K. Henney Radio Engin. Handbk. viii. 203 The coefficient showing the effect of plate voltage on the grid current has been termed inverse mutual conductance, or the plate-grid transconductance. 1944Electronic Engin. XVI. 318 The transconductance between these two grids is negative. 1950Electronics Feb. 107/1 In push-pull amplifiers, triodes using this type of neutralization compare favorably with pentodes of the same transconductance as wideband amplifiers. 1981J. C. Sprott Introd. Mod. Electronics vii. 159 At the operating point [of a field effect transistor] the value of the forward transconductance,..and the output resistance,..can be determined. |
