System and method for reducing stress in a cascode common-source amplifier

摘要

A method of reducing stress in a cascode common-source amplifier including a first transistor and a second transistor connected in a cascode arrangement. The method includes providing an input voltage and a bias voltage to the first transistor and the second transistor, respectively, connected in the cascode arrangement, generating, based on the input voltage and the bias voltage, an output current, and equalizing stress associated with operation of each of the first transistor and the second transistor. Equalizing the stress includes, in response to the input voltage decreasing by an amount sufficient to cause the first transistor and the second transistor to turn off, equalizing respective voltage drops across the first transistor and the second transistor.
