is the “silicon bandgap temperature sensor“. Instead of a diode, two transistors are used, and common-mode imperfections are cancelled out with an op-amp. This works great in an IC ...

Most electronic engineers know that a transistor’s base-emitter voltage (V BE) has a temperature coefficient (TC) of about -2 mV/°C. However, for precision temperature sensors, “about” isn ...

Accurate and cost-effective sensing of the temperature to be controlled. Closure of the feedback loop between temperatures sensor and heat and/or cooling ... lags common in thermal control systems.

Two papers at the International Solid-state Circuits Conference tackled ultra-low power on-chip temperature sensing, one using an npn transistor and the other by sensing a wire. The npn sensor ...

Multiplexing a bipolar power transistor between temperature self-measurement ... calibration (and recalibration if the sensor ever needs replacement). But then he saved the day with an ingenious ...

An 80V small signal transistor has been launched to address high temperature sensor interfaces such as piezoelectric sensors or to implement a guard amplifier. Cissoid's 'Mercury' mosfet transistor is ...

Graphene — a single layer of carbon atoms packed in a hexagonal lattice — has a number of appealing properties owing to its two-dimensional ... magnetic field sensors,” says Tan.
