Abstract
A control circuit, of a control loop, for a lighting driver. The lighting driver is adapted to controllably connect an electronic ballast to an LED light source or lamp. The control circuit comprises a biasing circuit having an adjustable impedance. A tuning circuit adjusts the impedance of the biasing circuit so as to tune a parameter of a frequency response of the control loop and thereby of the lighting driver.
