Analog buffers composed of thin film transistors

An analog buffer, comprising:

• a first source follower receiving an input voltage and providing an offset input voltage and an input offset voltage;
• a second follower receiving the offset input voltage, and providing an output voltage by compensating the offset input voltage with an output offset voltage;
• and
• a switching circuit coupled to the first source follower and the second source follower, the switching circuit providing the output offset voltage to the second source follower, and the switching circuit stores and equalizes the output offset voltage to the input offset voltage, thereby reducing offset in the output voltage.

A method of regulating voltage in an analog buffer, comprising the steps of:

• providing an offset input voltage and an input offset voltage in accordance with an input voltage;
• providing an output offset voltage, wherein the output offset voltage is equalized to the input offset voltage;
• and
• providing an output voltage, by compensating the offset input voltage with the output offset voltage, thereby reducing offset in the output voltage.
