SUMMARY Distortion analysis of nonlinear circuits is very important for designing analog integrated circuits and communication systems. In this letter, we propose an efficient frequency-domain approach for calculating frequency response curves, which is based on HB (harmonic balance) method combining with ABMs (Analog Behavior Models) of Spice. Firstly,(More)
We present a case of a patient who needed rapid switch from intra-aortic balloon pumping (IABP) to percutaneous cardiopulmonary support (PCPS)/venoarterial extracorporeal membrane oxygenation. It is difficult to switch from IABP to PCPS, because 0.035-inch guidewires cannot pass the IABP guidewire lumen (0.025-inch compatible), and the IABP sheath needs to(More)
BACKGROUND Peripheral venoarterial extracorporeal membranous oxygenation (ECMO) support is effective in patients with cardiogenic shock or fatal arrhythmia due to fulminant myocarditis. The clinical courses of fulminant myocarditis are still uncertain; therefore, it is difficult to determine the appropriate time for discontinuing ECMO or converting to a(More)
SUMMARY For designing integrated circuits and communication systems, it is very important to obtain the frequency-domain characteristics of nonlinear circuits. There are two kinds of the time-domain and frequency-domain methods. Although, first one can get the accurate steady-state waveform, it is unsuitable to calculate the frequency response curve [1,2].(More)
