  • Stacked pre-driver amplifier
    Patent number: 8106711
    Abstract: A stacked pre-driver stage and a power amplifier including the stacked pre-driver stage are described. The stacked pre-driver stage comprises stacked pre-drivers arranged in series between a supply voltage and a reference voltage. Each pre-driver includes a pre-driving amplifier, together with MOS transistors. Each pre-driver is subject, in operation, to a voltage difference which is inferior to a maximum allowed use voltage of the MOS transistors with a largely reduced voltage drop across the regulator included in the power amplifier.
    Type: Grant
    Filed: November 12, 2009
    Date of Patent: January 31, 2012
    Assignee: Peregrine Semiconductor Coporation

  • Electronic switch with static control voltage for dynamically switching capacitance in a frequency-adjustable crystal oscillator
    Patent number: 6559730
    Abstract: A controllable crystal oscillator includes a crystal resonator having first and second electrodes, a gain stage having first and second terminals connected to the first and second electrodes for starting and maintaining the oscillation, first and second capacitor banks connected to the first and second terminals for providing a capacitive load to the resonator, and first and second dynamic switches interconnected between the terminals and the respective capacitor banks for cycling the capacitor banks in and out of connection.
