The dirt simple way is an NPN transistor. Emitter to ground, collector through the load to the positive supply. A 10K resistor at the base to limit current and isolate the circuit from the load. The advantage here is that you can control a 12 or 24 volt load with a 5V positive signal...
The fundamental op amp circuit (Fig. 13 above) employs an NPN transistor and an op-amp to generate an output proportional to the input's log: VOUT = (- k log10) VIN/RIo The "inverted" circuit, working as a fundamental anti-log amplifier, is depicted in the lower diagram. Typically, ...
In a real circuit, the emitter of the output transistor would be connected to a capacitor. The other terminal of the capacitor would be connected to ground. There are several types of switching regulators. The switching regulator most like the linear regulator above is the 'buck' regulator. ...
