Abstract
Circuits to provide phase-cut analog dimming of solid state light sources are presented. Each circuit comprises an anchoring circuit to communicate with a dimming controller circuit, the anchoring circuit having a proportional direct current (DC) voltage input, a biasing voltage input, a connection to a ground reference, and an output in communication with a dimming controller circuit. The anchoring circuit provides a reference voltage to permit phase cut dimming to be operable at a plurality of line voltages.
