ABSTRACT:
A digital to analog converter is disclosed which can operate with a high accuracy and can be fabricated at a highly integrated structure.
The converter comprises a voltage divider circuit dividing a reference voltage into a plurality of divided voltages, a plurality of P-channel field effect transistor switches for selectively extracting a higher potential part of the divided voltages and a plurality of N-channel field effect transistor switches for selectively extracting a lower potential part of the divided voltages, wherein both of P-channel and N-channel transistors operate in a triode-region.
