RESIDUAL PM and AM NOISE MEASUREMENTS, NOISE FIGURE and JITTER CALCULATIONS of 100 GHz AMPLIFIERS
We report the first definitive PM and AM noise measurements at 100 GHz of indium phosphide (InP) amplifiers operating at 5 K, 77 K, and room temperature. Amplifier gain ranged from +7 dB to +30 dB, depending on input RF power levels and operating bias current and gate voltages. The measurement system, calibration procedure, and amplifier configuration are described along with strategies for red...
متن کاملReducing oscillator PM noise from AM–PM noise correlation
Introduction: In most oscillators, the close-to-the-carrier amplitude modulation (AM) noise is usually lower than the phase modulation (PM) noise and does not pose serious problems. However, in highperformance systems where every decibel of PM noise is important, the AM noise cannot be neglected. Numerous applications consider AM noise effects on the overall performance of an oscillator or a sy...
متن کامل100 MS/s 10-25 MHz Wireless Voltage Probe
For developing and testing of power electronic converters and circuits, voltages and currents have to be measured to verify the proper mode of operation. In cascaded converters or multi-level topologies, the voltages to be measured contain common mode components up to several kV with transients up to several tens of kV/μs. Conventional isolated voltage measurement systems do either not meet the...
متن کاملA New Low - Noise 100 - MHz Balanced Relaxation Oscillator
Abstrnct -A new fully balanced architecture for high-frequency, lownoise relaxation oscillators is presented. Differential operation is achieved with the use of two grounded capacitors utilizing the circuit parasitics. Bypassing of the regenerative memory function in the oscillator benefits both high-speed and low-noise operation. In addition a detailed analysis of phase noise in relaxation osc...
متن کاملAm and pm noise analysis in quartz crystal oscillators: symbolic calculus approach
Increasing performance of quartz crystal oscillators as well as predictability requirements when developing the devices need accurate analysis of noise sources. Our work is devoted to understand how an oscillator reacts to additive noise of an element in the electronic circuit. Up to now, oscillator designers often refer to the well-known Leeson’s model to explain the shape of phase noise spect...
