Abstract
Switches (such as FET's and other devices) are often used in circuits to generate an AC signal from a DC supply input. There are times when the supplied DC voltage is greater than desired for the ratings of the switches that can or must be used. There are also times when there may be voltage surges or other transient high voltage conditions for which it is desired to have greater margin between the voltage applied and the switch ratings. The circuit described applies across any of the switches a maximum of one half of the supplied DC voltage. The circuit may also be operated in a linear mode for use with analog signals.
