Abstract: Disclosed is circuitry for operating a switch which sees high voltage swings across its source, gate, drain, and bulk terminals. The circuitry generates one or more bias voltages in proportion to an input voltage swing. The one or more bias voltages may be used to bias the gate and bulk terminals to provide reliable and improved turn OFF performance in the switch.

Abstract: A method and apparatus for linearizing a baseband filter are provided. The apparatus is configured to, via a first conducting module, receive a first current signal. The apparatus is further configured to, via a converting module, receive a second current signal, generate a voltage signal based on the second current signal, and apply the voltage signal to the first conducting module. An amount of the second current signal received by the converting module is based on an amount of the first current signal flowing through the first conducting module. The apparatus is also configured to, via a second conducting module, control an output current signal based on the voltage signal. The output current signal is controlled to be a linear replica of the first current signal for in-band frequencies.
