Description

technical field [0001] The invention relates to the technical fields of voltage conversion and digital-to-analog conversion, in particular to a decoding and converting device and a digital-to-analog converter using the decoding and converting device. Background technique [0002] Voltage conversion circuits are usually used to convert low-voltage control signals into high-voltage control signals. For example, when applied to liquid crystal displays, it is usually necessary to convert digital control signals from low voltage to high voltage to drive thin-film transistors. The corresponding operation needs to be completed through a voltage conversion circuit. [0003] figure 1 It is a schematic diagram of the existing decoding and converting device 100. When the data A[1:0] is input, its high potential and low potential are respectively VCC and VSS. After passing through the decoder 110, decoding signals S0-S3 are respectively generated, wherein The high potentials and low p...
