“…However due to nonlinear behaviour of the semiconductors, including the dependence of β on the collector current [10], the effective resistance will be a more complex nonlinear function. Reference [11] suggests a methodology for analyzing the nonlinear behaviour of the circuit. However this discussion is beyond the scope of this paper.…”

A technique for a continuously variable AC resistance using a series BJT array is presented. This array provides high power dissipation capability and uniform voltage and power distribution across the individual transistors. The array, controlled using a set of optoisolators to maintain the electrical isolation between the control circuits and the power stage, could be used as the basis to develop several useful techniques including a solid state AC regulator with comparable performance to the commonly used ferro-resonant systems; a linear AC electronic load suitable for testing UPS and other power conditioners; and, in other AC power control applications such as switching capacitors in AC resonant circuits.A power sharing series power BJT array with isolated low voltage control for AC power control applications

Substituting (8) and (9) into (13), and expanding as a Volterra series in (14) where " " denotes the Volterra operator [25, p. 549], and where , , and are the parametric input frequencies within the Volterra formalism, one can solve successively for the kernels , , and in the customary way [28, pp. 178-186].…”

“…O VER THE years, the problem of high-frequency distortion in bipolar transistors has been extensively studied. Among the earlier works, Narayanan [1], [2] was the first to present a detailed examination of distortion using Volterra series; Chisholm and Nagel [3] and Kuo [4] focused on computer algorithms for calculating distortion in transistor circuits; Poon and Narayanan [5]- [7] combined Volterra series with a charge-control approach; Abraham and Meyer [8] employed a simplified transistor model to suggest design guidelines for low distortion; and many others contributed to the literature, as cited by these authors, and in a comprehensive review paper by Lotsch [9]. More recently, Maas et al [10] attributed the surprisingly good linearity of heterojunction bipolar transistors (HBTs) working at high frequencies to a cancellation of nonlinear currents arising from the dynamic resistance and capacitance of the emitter-base junction.…”

High-frequency distortion in bipolar transistors is examined by using the charge-control approach of Poon and Narayanan to connect the device's distortion behavior to its "loaded" unity-current-gain frequency (^). The resulting expressions for the distortion reveal considerable information on its frequency and bias dependence. Points on the^versus collector current curve yielding optimum distortion performance are identified and interpreted in terms of current cancellation. Both second-and third-order distortion are considered, and the results are validated by both simulation and experiment.
