Patent ID: 6879141

Claim:
A method for developing a temperature compensated voltage supply comprising the steps of: generating a first base voltage (VTC1) and a second base voltage (VTC2), wherein the first base voltage (VTC1) and the second base voltage (VTC2) have unique temperature coefficients (TC1, TC2); generating an output voltage (Vnew) by summing the first base voltage (VTC1) and the second base voltage (VTC2) assigned with different weights (a,b), such that the new output voltage Vnew has a new temperature coefficient TCnew; and this output voltage (Vnew) satisfies the expression: Vnew=a×VTC 2 +b×VTC 1, where the above two weight values (a,b) shall satisfy the conditions: a+b=1, and 0≦|a|, 1≧|b|.
