“…Most temperature-aware circuit designs use either mutual cancellation of different parameters [18], or ZTC biases [12] to achieve a low temperature coefficient of a given parameter. Both strategies come with different advantages and drawbacks.…”

“…5 illustrates the equivalent inductance sensitivity range from temperatures ranging from -40 • C to 175 • C.This figure shows a ZTC point of the average temperature sensitivity at V ctrl1 ≈ 0.7 V. However by biasing M 5 in ZTC, the VCO loses its frequency control characteristics. Fig 5 also shows an almost constant temperature sensitivity around 1.3 in the region from V ctrl1 between 0.3 and 0.6 V. This constant temperature sensitivity can be compensated by the C var temperature sensitivity using(18) to achieve a frequency ZTC point and still allow for VCO control as presented on[15].…”

The advent of the Internet-of-Things brings new challenges in circuit design. The presence of circuits and sensors in harsh environments brought the need for methodologies that account for them. Since the beginning of the transistors, the temperature is known for having a significant impact on performance, and even though very low temperature sensitivity circuits have been proposed, no general methodology for designing them exists. This paper proposes a general gm over Id technique for designing temperature-aware circuits that can be used either on measurement data, analytically, or based on simulation models. This model is validated using measurements up to 250°C of X-FAB XT018 transistors and later with a circuit design example.
