MOSFET amplifier with dynamically biased cascode output

An apparatus including a metal oxide semiconductor field effect transistor (MOSFET) amplifier with dynamically biased cascode output circuitry, comprising:

• first and second power supply terminals to convey first and second voltages defining a power supply voltage;
• telescopic cascode amplifier circuitry, coupled between said first and second power supply terminals, that responds to reception of a current source bias voltage intermediate said first and second voltages, an input signal centered about an input baseline voltage intermediate said first and current source bias voltages, and at least one cascode bias voltage intermediate said first and input baseline voltages by providing a first internal bias voltage intermediate said current source bias and input baseline voltages, a second internal bias voltage intermediate said input baseline and at least one cascode bias voltages, and an output signal corresponding to said input signal and centered about an output baseline voltage intermediate said first and cascode bias voltages;
• first voltage replication circuitry, coupled to said telescopic cascode amplifier circuitry, that responds to reception of said input baseline voltage and a first bias current by providing said current source bias voltage and a first replica bias voltage substantially equal to said first internal bias voltage;
• and
• first voltage translation circuitry, coupled to said first voltage replication circuitry and said telescopic cascode amplifier circuitry, that responds to reception of said current source bias voltage, said first replica bias voltage and a second bias current related to said first bias current by providing a first one of said at least one cascode bias voltage.
