This article provides information about an SCR based ESD protection clamp for RF circuits validated in TSMC 90nm CMOS technology. The ESD protection clamp described has excellent figures of merit: Due to the low parasitic capacitance, low leakage and high Q-factor the influence on the RF performance is limited.
Many medical/healthcare applications rely on semiconductor chips, certainly for the mobile and connected devices. Silicon chips enable a fast evolution and widespread use of new applications. However, integrated circuits (IC) used in medical applications require special attention for Electrostatic Discharge (ESD) protection.
Semiconductor circuits used for Near Field Communication (NFC) need to be protected against excessive voltage. Two different approaches are discussed.
