The heart of the device that [Kerry] designed is based on 6 power MOSFETs, a few operational amplifiers ... the latter allows a constant power load mode (as power = current * voltage).

Typically, pulse width modulated amplifiers are used to emulate linear constant voltage amplifiers or linear constant current amplifiers. PWM amplifier chips consume less power than these linear ...

That was a constant current load, not a constant resistance load. [YS] started with the schematic for the Re:load and made his changes to arrive at this. For him the exercise was just to alter the ...

Current-feedback operational amplifiers are devices where ... Conventional Voltage-Feedback Op-Amp and the Constant Gain Bandwidth Product Paradigm A conventional voltage-feedback operational ...
