Abstract
Amplifier embodiments are provided that are well suited for systems which require high signal gains and high transient currents that can drive various loads (e.g., capacitive loads). At least one amplifier embodiment is realized with a cascoded complementary differential input stage, a complementary differential output stage, and a bias controller. The output stage includes lower and upper differential pairs of transistors that respectively have lower and upper coupled back gates and the bias controller is configured to provide bias voltages for the lower and upper coupled back gates.
