Abstract: The low-power relaxation oscillator comprises a first module (21) having a ramp generator formed by a reference current source (31) and a storage capacitor (32) defining a ramp voltage (Vramp1), and a voltage comparator (m1, m2) for comparing the ramp voltage with a reference voltage, a second module (22, 41, 42, Vramp2, m3, m4) similar to the first module and an asynchronous flip-flop (23) receiving the output signal of the comparator of the first module at a first input (s) and the output signal of the comparator of the second module at a second input (r). For each module a generator of said reference voltage is configured by adding a reference resistance (33, 43) between the reference current source and the storage capacitor. Thus, the generation of the reference voltage and the ramp voltage is conducted on the very same current branch. This enables the electrical power consumption of the oscillator to be reduced.

Abstract: The electronic circuit for measuring at least one physical parameter supplies an analogue output measurement signal (SA) dependent upon the value of a supply voltage. The circuit includes a sensor interface, connected to a sensor for supplying an analogue measurement signal (Vm) which is then filtered, an analogue-digital converter for digitally converting the filtered signal (Sm), and a digital signal control and processing unit for receiving a converted signal from the converter and supplying a digital measurement signal (SD). The sensor interface, the analogue-digital converter, and the processing unit are powered by a voltage regulator. The analogue and digital measurement signals are thus independent of any variation in the supply voltage (VCC) of the electronic circuit. A ratiometric unit, which may be an analogue multiplier or an analogue-digital converter, is powered by the supply voltage source (Bat) to recreate ratiometry on SA on the basis of Sm or SD.

The selected material may be, for example, a material having an amorphous structure, such as a metallic glass.
