Wong Ting Wah, Woo Chong L: Integrated radio frequency circuits. Programmable Silicon Solutions, March 12, 2003: EP1291918-A2 (12 worldwide citation)

An RF circuit (310) may be formed over a triple well (316, 318, 320) that creates two reverse biased junctions. By adjusting the bias across the junctions, the capacitance across the junctions can be reduced, reducing the capacitive coupling from the RF circuits (310) to the substrate (316), improvi ...
