Abstract:
Provided is a decoder for receiving a digital data and outputting an analog voltage. The decoder comprising a main switch array, a first pre-decoding switch array, and a second pre-decoding switch array. The main switch array receives the digital data and outputs a voltage if the digital data is in a first range. The first pre-decoding switch array is for receiving the digital data, pre-decoding a part of the digital data, and outputting a voltage if the digital data is in a second range. The second pre-decoding switch array is for receiving the digital data, pre-decoding the part of the digital data, and outputting a voltage if the digital data is in a third range. Combination of the main switch array, the first pre-decoding switch array, and the second pre-decoding switch array is in a substantially rectangular layout structure.
