Abstract :
Trench guard technology was proposed to suppress the coupling between inductors, and to reduce crosstalk in silicon RF ICs. The test structure adopting a deep trench guard ring showed a coupling less than -40 dB in the frequency range of 0.5-20 GHz, and negligible change in designed inductance value up to 10 GHz. Furthermore, it can be also used to isolate a noisy circuit block from other quiet blocks in mixed signal silicon RF ICs.
