A method comprising providing feedback to a base of a transistor of an emitter-follower circuit, the providing proportional to both amplitude of a collector current and frequency of the collector current.
A system comprising:
- a signal source providing a signal;
- a transistor having a base, emitter and collector, the collector coupled to a supply voltage source and the base coupled to the signal source;
- a load coupled to the emitter;
- and
- a feedback circuit coupled to the base, the feedback circuit provides a feedback signal to the base proportional to both the amplitude and frequency of current at the collector;
- wherein a peak-to-peak voltage of the signal provided by the signal source to the base resistor is greater than a peak-to-peak voltage of a signal in the collector.
