Abstract
An open loop process and temperature independent bias circuit for stacked device amplifiers is disclosed herein. In one or more embodiments, a method for biasing a stacked high-voltage signal amplifier with a voltage divider bias module comprises generating, by the voltage divider bias module from a power supply voltage (VDD), a plurality of control voltage biases, which comprise a plurality of voltage references plus an offset voltage term (Vtemp). In one or more embodiments, the plurality of voltage references are each proportional to a division of the power supply voltage (VDD), and the offset voltage term (Vtemp) is proportional to temperature and is a function of process variation. The method further comprises biasing, a plurality of devices of the stacked high-voltage signal amplifier, with the control voltage biases.
