In summary, DiffAmpCalc™ is an interactive design and parametric simulation tool for differential amplifiers, for use in driving high performance ADCs. A DiffAmpCalc design requires only four steps; select the amplifier, choose a topology, specify the gain, and specify the input voltages. The user can also optimize the design for specifications such as input/output dynamic range, power dissipation, supply voltages, bandwidth, noise and distortion. If high differential gain is required, DiffAmpCalc allows the user to manually connect multiple stages and evaluate the designs.
