ABSTRACT:
A temperature compensated technique and circuit can be realized through the generation of a temperature compensated output voltage (Vnew) provided after summing the temperature coefficients (TC1,TC2) of two base voltages (VTC1, VTC2) assigned with different weights (a, b) and producing a new temperature coefficient (TCnew). This TCnew satisfies the expression: TCnew=TC1+a×(TC2−TC1), where the assigned weighted value (a) can be either a positive or a negative value, depending on the requirement of a circuit, in order to develop voltage supply suitable for wider applications.
