Abstract:
1. A digital-to-analog data converter for converting a digital input signal into an analog output signal, the digital-to-analog data converter comprising: a register for receiving and registering the digital input signal, wherein the digital input signal comprises most significant bits and least significant bits; a decoder electrically connected to the register for decoding the least significant bits and taking the decoded least significant bits as a first control signal during a first period, and decoding the most significant bits and taking the decoded most significant bits as a second control signal during a second period; a converting unit electrically connected to the decoder for outputting a first converting current according to the first control signal during the first period, and outputting a second converting current according to the second control signal during the second period; and an output unit electrically connected to the converting unit for registering the first converting current during the first period, amplifying the second converting current and combining the amplified second converting current with the registered first converting current as the analog output signal during the second period.
