Abstract
A plurality of devices, such as devices that are utilized for implementing radio frequency applications, can be formed in the same substrate. Each of these devices may be formed over a triple well that includes at least one well capable of being biased. Each of the wells is coupled to a well bias through a resistor. In some embodiments, a plurality of wells operating at a relatively high frequency may be connected to the same bias potential, each through separate resistors. The noise coupling may be reduced through the use of the bias resistors.
