Abstract:
A temperature and process compensated circuitry system comprising:a first transistor having a first terminal coupled to a first voltage source, a second terminal coupled to a first input, and a third terminal coupled to a first end of a first resistor; a second transistor having a first terminal coupled to ground, a second terminal coupled to a second input, and a third terminal coupled to a first end of a second resistor; a third transistor having a first terminal coupled to an output, a second terminal coupled jointly to a second end of said first and second resistors, and a third terminal coupled to ground; a third resistor, coupled at a first end to said output and at a second end to a second voltage source; a feedback circuit coupled between said output and the second terminal of said third transistor; and a reference circuit coupled to said feedback circuit.
