Logarithmic DAC with diode |
摘要 |
<p>Systems and methods to achieve a logarithmic digital-to-analog converter (DAC), which is easy to be implemented, and requiring reduced chip space have been disclosed. The logarithmic DAC is created by a simple and easy to scale linear DAC, which is linearly scaling a predefined voltage range. The output voltage of the linear DAC is converted to a logarithmic current value directly by the voltage-current characteristic of an integrated diode.</p> |
