Abstract
An LED current regulator can regulate an LED current of an encoder system. The LED current regulator may comprise a first analog multiplier and a second analog multiplier. Each of the first and second analog multipliers may be configured to receive respective photodetector output signals, characterized by a peak-to-peak voltage, Vpp, and may be configured to generate respective first and second multiplier output signals. The first and second multiplier output signals may be combined to produce a first DC level, which may be representative of the peak-to-peak voltage, Vpp, of the photodetector output signals.
