“…Under the same starting conditions, the critically damped system always returns faster to its equilibrium than the overdamped system. An oscillation is observed when (9) In this case the solution contains a time varying complex exponential function, which means the system is oscillating over time. The real part of the generic solution can then be written as 10where and are coefficients depending on the boundary conditions of the differential equation.…”

“…a wireless sensor network [7] and [8], RC-based oscillators are preferred rather than the LC-based topologies. A solution for this kind of application can be found using a well-known harmonic oscillator structure: the Wienbridge oscillator [9]- [11]. The use of an improved topology makes it possible to realize a low phase-noise and temperature insensitive Wienbridge oscillator.…”

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. The noise as well as temperature behavior of the oscillator is explained using extensive calculations. Measurements on 7 samples of the same batch show a temperature stability of 86 ppm C and a measured spread of 0.9% at an oscillation frequency of 6 MHz. The circuit consumes 66 W and is realized in a 65 nm technology measuring 150 m by 200 m. The measured phase noise figure of merit is 172 dB at a frequency offset of 100 kHz.

“…Since a low-power, low-frequency time reference is desired in lowpower WSNs, RC-based oscillators are preferred rather than the LC-based topologies [218,224]. A solution is found using a well-known harmonic oscillator structure: the Wien bridge oscillator [22,32,219]. As will be shown, however, the classical Wien bridge design using an operational amplifier is not suitable when external parameters such as supply voltage and temperature are varying.…”
