This paper presents a state-of-art ESD protection design for RF circuit with a human-body-model (HBM) ESD robustness of 8kV. By including a turn-on efficient power-rails clamp circuit into the RF circuit, the ESD clamp devices of the RF input pin are operated in the forward-biased conduction, rather than the traditional junction breakdown condition. Therefore, the dimension of ESD devices for the RF input pin can be further downsized to reduce the input capacitance loading for the RF signal. This design has been successfully applied in a 900-MHz RF receiver and fabricated in 0.25-μm CMOS process with a thick top metal layer. The experimental results have confirmed that its ESD robustness is as high as >8kV under the HBM ESD test.
