Abstract
An ECL bandgap reference voltage generator includes a supply-independent current source (14) to produce an output reference voltage (V.sub.BB) that is independent of variations of supply voltage but yet without consuming additional power dissipation. The supply-independent current source (14) is formed of a pair of transistors (Q907, Q908) and first through third resistors (R903, R904, R908).
