  • Input amplifier with improved power supply rejection
    Patent number: 7180371
    Abstract: An input amplifier for power amplifier control circuitry includes an input, an output, a power supply voltage, a ground, a differential amplifier and a double folded cascode and conversion stage. The differential amplifier is connected to the input, to the power supply voltage and to the ground. The differential amplifier provides a differential output. The double folded cascode and conversion stage is connected to the differential amplifier, to the ground and to the power supply voltage. The double folded cascode and conversion stage converts the differential output to a single-ended signal. The double folded cascode and conversion stage is optimized to prevent variation in the power supply voltage from propagating to the output.
