摘要
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 ((ω) over cap (T)). The resulting expressions for the distortion reveal considerable information on its frequency and bias dependence. Points on the COT 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.
