ABSTRACT:
Each of a pair of PN junction diodes (D.sub.1 ; D.sub.2) is separately dynamically biased by a different clocked current source arrangement (C.sub.1, M.sub.2 ; C.sub.2, M.sub.5). The resulting diode voltage drops (V.sub.1 and V.sub.2) are fed through a weighted difference amplifier (A; C.sub.3, C.sub.4, C.sub.5, C.sub.6) to produce a voltage reference V.sub.OUT which is relatively insensitive to temperature variations of the semiconductor body in which the PN junction diodes are integrated.
