An OTA-Based Digital-To-Analog Converter [PDF]

Active and Passive Electronic Components, 1994
A simple circuit for implementing a current-switching digital-to-analog converter is presented. The circuit uses operational transconductance amplifiers (OTAs) for switching a number of equal-value current sources.

Mismatch-Shaping Serial Digital-to-Analog Converter [PDF]

ISCAS'99. Proceedings of the 1999 IEEE International Symposium on Circuits and Systems VLSI (Cat. No.99CH36349), 1999
A simple but accurate pseudo-passive mismatch-shaping D/A converter is described. A digital state machine is used to control the switching sequence of a symmetric two-capacitor network that performs the D/A conversion. The error caused by capacitor mismatch is uncorrelated with the input signal and has only little power in the signal band.

Challenges and implementation aspects of switched-mode power supplies with digital control for automotive applications [PDF]

Advances in Radio Science, 2016
Switched-mode power supplies (SMPS) convert an input DC-voltage into a higher or lower output voltage. In automotive, analog control is mostly used in order to keep the required output voltages constant and resistant to disturbances. The design of robust
