"This paper presents the design of a new Wienbridge topology. Its phase noise performance, low temperature dependency and low power consumption make it suitable for use in wireless sensor nodes and time-based sensor readout circuitry," investigators in Leuven, Belgium report.
"The noise as well as temperature behavior of the oscillator is explained using extensive calculations. on 7 samples of the same batch show a temperature stability of 86 ppm/degrees C and a measured spread of 0.9% at an oscillation frequency of 6 MHz," wrote V. Desmedt and colleagues, University of Leuven.
The researchers concluded: "The circuit consumes 66 mu W and is realized in ...
