6 Summary. Low-power electronic circuits are important for portable devices. Semiconductor devices are at the heart of these circuits with MOS devices making up the majority of today's integrated circuits. In digital circuits, the MOSFET can be considered a switch, but it is a nonideal switch with an "on" resistance and limited current ...

The MOSFET will have less IR drop when 'on' (only Rds (on)) than a BJT (Vce (sat)). Also, the BJT has base current, while FET gate current is essentially zero. However, when off, the FET might have more leakage than the BJT - check the datasheets of the comparable FET vs. BJT devices. That said, there are ultra-low power load …

Lowering the Voltage. One of the easiest ways to reduce current is to lower the voltage you give to the Arduino. Just by reducing the voltage from 5V to 3.3V, the current drops from ~4mA, down to ~1mA! Reducing the voltage, does have a catch though. Reducing the system voltage too much, without reducing clock speed, could make the ...
