Abstract
Apparatus and methods to increase the range of a signal processing circuit. A system uses floating bias circuits coupled to a signal processing circuit to increase the range of power supplies that can be used with the signal processing circuit, while maintaining the components of the signal processing circuit within a breakdown voltage threshold. As the voltage level of the data signal varies, the voltage level of the floating bias circuits varies as well.
