Abstract
Numerous examples are disclosed for performing calibration of various electrical parameters in a deep learning artificial neural network. In one example, a system comprises a digital-to-analog converter for receiving an input of k bits and generating a first analog output, a mapping scalar for converting the first analog output into a second analog output, and an analog-to-digital converter for generating an output of n bits from the second analog output, where n is a different value than k.
Claims4
A system comprising:
- a digital-to-analog converter comprising a high voltage source, a low voltage source, and a voltage ladder coupled between the high voltage source and the low voltage source, the voltage ladder providing a plurality of voltages;
- a mapping block for selecting and outputting as a voltage output one of the plurality of voltages in response to a digital input;
- and
- an output buffer for providing the voltage output as an output of the system.
