Abstract
An integrated circuit device includes an amplifier circuit that includes first and second differential transistor pairs that are selectively operable responsive to at least one bit of a multi-bit data signal.
Claims22
An integrated circuit device, comprising:
- an amplifier circuit comprising first and second differential transistor pairs that are selectively operable responsive to at least one bit of a multi-bit data signal.
A decoding circuit for a TFT LCD driver circuit, comprising:
- a first decoder that is configured to select a first gray scale voltage from n gray scale voltages responsive to m bits of a multi-bit data signal;
- and
- a second decoder that is configured to select a second gray scale input voltage from the n gray scale voltages responsive to the m bits of the multi-bit data signal;
- wherein 2m<n.
