Patent ID: 7009374

Claim:
A bandgap reference circuit comprising: an operational amplifier including a first input, a second input, and a first output; a T-network of passive resistors electrically connected between said first and said second inputs, wherein said T-network includes: a first resistor having a first terminal and a second terminal, wherein said first terminal is electrically connected to said first input, a second resistor having a third terminal and a fourth terminal, wherein said third terminal is electrically connected to said second terminal and said fourth terminal is electrically connected to said second input, and a third resistor having a fifth terminal and a sixth terminal, wherein said fifth terminal is electrically connected to at least one of said second and said third terminals and said sixth terminal is electrically connected to a reference potential; and a transistor network having a third input and a second output, wherein said first output of said operational amplifier is electrically connected to said third input to generate a bandgap reference voltage at said second output.
