    摘要: Analog buffers with a precise gate to source voltage compensation and a small DC offset, by storing an input offset voltage to be used as an output offset voltage to reverse the offset in the input. A first source follower at the input end and a second source follower at the output end are both coupled to a switching circuit, wherein the first follower provides an input offset voltage (e.g., |Vgsp|) based on the input voltage (Vin), the second source follower provides an output voltage (Vout) by compensating Vin transmitted through the analog buffer circuit with an output offset voltage (|Vgsn|), and the switching circuit stores and equalizes the output offset voltage to the input offset voltage (|Vgsp|=|Vgsn|), so to obtain an output Vout that is identical to Vin.
