Abstract
A voltage reference circuit including a resistive track having a first force contact and a second force contact. The first and second force contacts configured to pass a current through the resistive track. A first sense contact, a second sense contact and a third sense contact are arranged at different positions along the resistive track between the first and second force contacts and the sense contacts are arranged to define a first resistor and a second resistor. A first component arrangement includes a P-N junction which has a temperature dependent voltage bias; a second component arrangement. One or both of the first component arrangement and the second component arrangement provide for a counter-bias voltage. The counter bias voltage counters the temperature dependent voltage bias of the P-N junction such that the voltage reference circuit provides a constant output reference voltage.
