  • Abstract
    A dc-coupled unity-gain buffer amplifier capable of zero offset is described. Using a dual MOST device in a bootstrapped differential source-follower configuration, together with a monolithic integrated circuit amplifier, it has an input current of 13 × 10-15A and a 3 dB bandwidth of 4 MHz. Drift is approximately 100 µV/°C and input capacity 0.4 pF.
