<p>A temperature compensated low voltage reference circuit can be realized with a reduced operating voltage overhead. This is accomplished in several ways including minimizing drain voltage variation at the drains of two inter-connected transistors and implementing a current conveyer in order to adjust the temperature coefficient of an output current or voltage. Various combinations of voltage minimization and temperature coefficient adjustments may be used to design a reference circuit to a circuit designer's preference. A temperature compensated current source may also be created. The temperature compensated current source may be used to provide a wide range of output voltages. All of the reference circuits may be constructed with various types of transistors including DTMOS transistors.</p> |
