Low Power Startup Circuits for Voltage and Current Reference …

WebVoltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light. In brief, voltage = pressure, and it is measured in volts (V). The term recognizes Italian physicist Alessandro Volta (1745-1827), inventor of the voltaic ... Webof the circuit. After the current reference settles at its required operating state, M0 goes on and a constant current starts flowing through M0 and M1. Thus, the conventional startup circuit continues to consume current even after the current reference circuit is started. The value of this consumed current depends upon the startup time required.
