  • Publication number: 20190173278
    Abstract: An electrostatic discharge (ESD) protection circuit is provided. The ESD protection circuit includes a transient-state detection circuit configured to generate a dynamic triggering signal based on a voltage change rate of a voltage on a first power rail; a voltage detection circuit configured to generate a static triggering signal based on the voltage on the first power rail; a trigger circuit configured to generate a discharge control signal based on the dynamic triggering signal and the static triggering signal; and a main discharge circuit configured to discharge an electric charge from the first power rail to a second power rail based on the discharge control signal.

  • Patent number: 7420412
    Abstract: A multiple power mode amplifier provides a low and a high power mode without using switches. This amplifier may be used in radio frequency (RF) applications such as mobile telephones, pagers, portable digital assistants, and wireless e-mail devices. In the low power mode, the power consumption of the amplifier is reduced, which will increase operation time, especially important for battery-operated devices. In one implementation, the amplifier includes a number of impedance matching network units (130, 140, 150, and 160), impedance transformer (170), and a power stage (120). An implementation provides further power consumption savings by modulating a bias of an amplifier stage.
