Summary

An improved analysis for the bipolar linear transconductor, assuming a finite value for the transistor current-gain beta, is presented. A new expression for the normalized input-voltage as a function of the normalized output-current is obtained. A Fourier-series model is presented for this current-voltage relationship. Closed-form expressions are also derived for the harmonic and intermodulation components resulting from exciting the bipolar linear transconductor by a multisinusoidal input voltage. These expressions can be used to predict the limiting values of the input voltage amplitudes for a prescribed tolerable distortion percentage
