Abstract
An amplifier, including a voltage-to-current converter (V2I) to control an output current based on an input voltage, resistive degeneration circuitry to reduce baseband gain of the voltage-to-current converter, capacitive degeneration circuitry to increase passband gain of the voltage-to-current converter, and impedance control circuitry to compensate for negative input impedance of the capacitive degeneration circuitry. The V2I may include series-connected complimentary V2Is. The impedance control circuitry may include resistive negative feedback to provide a real part of input impedance, which may increase a frequency range for which the amplifier is linear. Capacitive degeneration and associated phase compensation may increase a frequency range for which the resistive feedback is negative. The amplifier may be configured as a single-input/single-output system and/or as a differential system.
