Transconductor: The specifications and technological parameters are given in figure 05. The calculated design pace for this set of specifications is shown in figure 06, where the green line represents the maximum allowable gain versus channel length for the specified technological parameters. The red curve represents constant cutoff frequency transistor. The cyan and blue lines represent the minimum and maximum inversion levels. The yellow region represents the design space, i. e., the region for which the specs are met. By selecting a point, all its characteristics are displayed at the right side of the screen. Fig. 05.
