Abstract:
An apparatus including an amplifier with Miller-effect frequency compensation, comprising:first amplification circuitry, including an internal terminal and a first output terminal, that receives and amplifies an input signal to provide a first amplified signal via said first output terminal, wherein said internal terminal has an internal terminal impedance associated therewith, said first output terminal has an output terminal impedance associated therewith, and said internal terminal impedance is substantially lower than said output terminal impedance; second amplification circuitry, coupled to said first output terminal and including a second output terminal, that receives and further amplifies said first amplified signal to provide a second amplified signal via said second output terminal; feedback capacitance coupled between said second output terminal and said internal terminal; and compensation circuitry coupled in shunt to said first output terminal and including capacitive and resistive circuit elements mutually coupled in series.
