Abstract:
1. A composite amplifier circuit configured for use within high-speed applications, said composite amplifier circuit comprising: a first amplifier having an inverting input terminal configured as an inverting input terminal for said composite amplifier circuit, and an output terminal configured as an output terminal for said composite amplifier circuit; a second amplifier configured as an integrator circuit, said second amplifier having a non-inverting input terminal configured as a non-inverting input terminal for said composite amplifier circuit, an inverting input terminal coupled through an integrator resistor to said inverting input terminal of said composite amplifier circuit, and an output terminal coupled to a non-inverting input terminal of said first amplifier; and a compensation circuit directly coupled between said output terminal of said composite amplifier circuit and said inverting input terminal of said second amplifier, said compensation circuit configured to provide a path for current needed by said integrator resistor due to any small signal appearing at said inverting input terminal for said composite amplifier circuit.
