BiCMOS Colpitts Oscillator for Vector- Sum Interpolators
Purpose – The demand for higher bandwidth has resulted in the development of mm-wave phased array systems. This paper explores a technique that could be used to feed the individual antennas in a mm-wave phased array system with the appropriate phase shifted signal, to achieve required directivity. It presents differential Colpitts oscillators at 5 GHz and 60 GHz that can provide differential ou...
متن کاملColpitts Oscillator Circuit Diagram
Perhaps the simplest Colpitts oscillator to construct and get running. Because there is no load on the inductor a high "Q" circuit results with a high L/C. Colpitts Oscillator Tutorial and the theory behind the design of the Colpitts Oscillator which uses a LC Oscillator tank circuit to generate sine waves. The Colpitts Oscillator Circuit Characterised By Tapping The Midpoint Of The Capacitive ...
متن کاملControlling chaos in Colpitts oscillator
In this paper, an adaptive backstepping design is proposed to synchronize and control the Colpitts oscillator. The proposed control approach enables stabilization of chaotic motion to a steady state as well as synchronization by recursively interlacing the choice of a Lyapunov function with the design of feedback control in a systematical way. Numerical simulations verify the effectiveness of t...
متن کاملTowards Threshold Frequency in Chaotic Colpitts oscillator
A novel version of chaotic Colpitts oscillator is described. Instead of a linear loss resistor, it includes an extra inductor and a diode in the collector circuit of the transistor. The modified circuit in comparison with the common Colpitts oscillator may generate chaotic oscillations at the fundamental frequency f∗ noticeably closer to the threshold frequency fT of the employed bipolar juncti...
متن کاملAsymptotic synchronization of the Colpitts oscillator
In this paper we deal with the observer-based asymptotic synchronization problem for a class of chaotic oscillators. Some results based on a differential algebraic approach are used in order to determine the algebraic observability of unknown variables. The strategy consists of proposing a slave system (observer) which tends to follow asymptotically the master system. The methodology is tested ...
