摘要： A chopper stabilized bandgap voltage reference circuit comprises current mirror circuitry mirroring first and second currents into first and second networks to generate a forward diode voltage signal and a PTAT (proportional to absolute temperature) component signal, and a third current having a derived temperature coefficient into a third network to generate a reference voltage signal for a regulator. An amplifier amplifies a differential signal of the forward diode voltage signal and the PTAT component signal to output a fourth current to control the first and second currents. According to a chopper clock, a modulator modulates the differential signal to be supplied to the amplifier and a demodulator demodulates the fourth current. A gain loop compensation circuit is coupled to the demodulator to compensate the amplifier, and filter the fourth current for noise components, and a bypass circuit is also provided to the third network for filtering the third current.

摘要： A high-efficiency power amplifier module having a high breakdown resistance and a function of preventing an amplifier device from breaking down because of the standing wave due to reflection from an antenna end when the load varies. When the load varies, the overcurrent flowing through the base of a final-stage amplifying section GaAs-HBT is detected and canceled to suppress the collector current. Therefore an increase of the output is prevented, and the GaAs-HBT is prevented from breaking down. By using both the function that the idling current decreases with an increase of the power supply voltage and the clipping function of a diode parallel connected to the output-stage GaAs-HBT, an overvoltage higher than necessary and an overcurrent larger than necessary are prevented from being applied to the output-stage GaAs-HBT. The breakdown resistance of the power amplifier module is improved, and the device breakdown when the load varies is prevented. The manufacturing variation of the current amplification factor of the GaAs-HBT and the influence of the temperature variation are reduced. Therefore manufacturing yield is high and the manufacturing cost is low.
