DIGITAL-TO-ANALOG CONVERTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18223861 titled 'DIGITAL-TO-ANALOG CONVERTER
Simplified Explanation
- The patent application describes a digital-to-analog converter (DAC) that converts digital signals into analog voltage waveforms. - The DAC consists of multiple 1-bit elements, each of which outputs a current based on the value indicated by the input digital signal. - These 1-bit elements are connected to a capacitive load, which helps generate the analog voltage waveform. - Each 1-bit element includes a switching circuit that adjusts the bias of the voltage within the element based on the input digital signal. - The switching circuit also controls the connection and disconnection with a power supply based on changes in the bias. - The innovation in this patent application lies in the design and configuration of the 1-bit elements and the switching circuit, which enable accurate and efficient conversion of digital signals into analog voltage waveforms.
Original Abstract Submitted
A digital-to-analog converter includes a plurality of 1-bit elements each of which outputs a current corresponding to a value indicated by a digital signal when the digital signal is input; and a capacitive load connected to the plurality of 1-bit elements, the digital-to-analog converter being configured to generate an analog voltage waveform via the capacitive load that receives currents output from the plurality of 1-bit elements, wherein each of the 1-bit elements includes a switching circuit to change a bias of a voltage in each of the 1-bit elements according to a value indicated by an input digital signal, and to switch connection and non-connection with a power supply according to a change in the bias.
