To get around the built-in short-circuit protection he needed a potentiometer to limit the current while allowing for adjustments. His first circuit used a resistor salvaged from an AT supply and ...

A servo uses a potentiometer attached to the output shaft in order to sense position, and the internal electronics take care of driving the motor to move the shaft to the desired angle.

Design automation in this area is required urgently. This paper presents a highly portable and configurable Digital Controlled Potentiometer (DCP) IP core which comes along with a novel, mainly ...
