    摘要: An ESD protection circuit for an RF semiconductor device includes an RF input pad configured to receive an RF input signal having an RF operating frequency for the RF semiconductor device. A first ESD block is coupled between an intermediate node and the first power supply voltage terminal, to direct an ESD pulse of a first polarity toward the first power supply voltage terminal. A second ESD block is coupled between the intermediate node and the second power supply voltage terminal, to direct an ESD pulse of a second, opposite polarity toward the second power supply voltage terminal. A resonance circuit is coupled between the RF input pad and the intermediate node. The resonance circuit is configured to present a greater impedance to the RF input signal having the RF operating frequency than to the ESD pulses.

    摘要: A repair circuitry consisting of at least one electrical fuse forming part of a conduction path between a positive voltage supply (Vq) pad and a complimentary lower voltage supply source (Vss). The repair circuitry includes at least one switching device and at least one control circuitry. The at least one switching device has a control terminal and is coupled between the Vq pad and the at least one electrical fuse. The at least one control circuitry is coupled to the control terminal and the Vq pad respectively. Upon an application of a positive high voltage to the Vq pad, the control circuitry delays the turned-on state of the switching device for a predetermined period of time, thereby blocking stray currents occurred during ESD events. Consequently, the repair circuitry can prevent the at least one electrical fuse from being mistakenly programmed.
