A simple oscillator with perfect output power using a series feedback and circuit matching is proposed. The oscillator is implemented by tuning the positive feedback of the source and gate of the transistor and provides a free-running oscillating signal of 12 GHz. The output power of the oscillator is 10.16 dBm. This result is in good agreement with simulation.
In this letter, an efficient simplification scheme for modeling electromagnetic crosstalk of complex cable bundles above an orthogonal ground plane is proposed. Based on the image theory and wide separation assumptions, the solution of the per-unit-length inductance and capacitance matrices of the cable bundle in such an environment can analytically be obtained. A modified six-step procedure is established...
Aiming the great phase lag of the control-to-output small signal transfer function of LCC resonant converter, compensation networks composed of a band-stop filter and a single-pole-single-zero network are designed. Matlab and PSpice simulations are finished simultaneously, which verify that the output voltage can be regulated automatically in the disturbance of load changing. And good steady-state...
Since there is a great phase lag in the frequency characteristics of LCC resonant converter, a compensation network composed of a band-stop filter and a leading-and-lagging network is designed to stabilize the system. Simulation results verify that the output voltage can be regulated automatically under the disturbance of load changing and input fluctuation. And good steady-state accuracy and short...
