In summary, a LC phase shift oscillator is a circuit consisting of an op-amp, LC loop, and resistors. The op-amp has a reference voltage applied to the non-inverting end and the inverting end has a feedback resistor and Vout from the LC loop connected. The circuit works by using the...

One more way of satisfying the phase-difference condition is to use four RC networks, each offering a phase-shift of 45o. Hence it can be concluded that theRC phase-shift oscillatorscan be designed in many ways as the number of RC networks in them is not fixed. However it is to be ...
Ferrite phase shifters are usually two-port devices that provide a variable phase shift of the transmission path by changing the bias field of the ferrite. From: The Electrical Engineering Handbook, 2005 About this pageAdd to MendeleySet alert ...
In this work, a coupled-oscillator system with coupling networks containing discrete transmissions lines, made up of inductors and varactors, is presented. Under weak coupling conditions, it is possible to obtain two stable phase-shift intervals, -90° to 90° and 90° to 270°, by using two...
As a minimal model, we consider a single oscillator exhibiting a phase shift: $$\begin{aligned} x(t) = \cos \left( \hat{\omega }_1 t + u(t) \right) , \quad \frac{du(t)}{dt} = {\left\{ \begin{array}{ll} \sigma \eta (t) &{} \textrm{for} \quad t \notin [T_c...
