The degree of parasympathetic heart rate control, PC, was defined as the decrease in average heart period (RR interval) caused by the elimination of parasympathetically mediated influences on the heart while keeping sympathetic activity unchanged. By reviewing published results on the interaction of sympathetic and parasympathetic heart rate control, the… (More)
— A new CMOS current readout structure for the infrared (IR) focal-plane-array (FPA), called the buffered gate modulation input (BGMI) circuit, is proposed in this paper. Using the technique of unbalanced current mirror, the new BGMI circuit can achieve high charge sensitivity with adaptive current gain control and good immunity from threshold-voltage… (More)
A test socket chip for measuring dark currents of infrared (IR) detectors in a focal plane array (FPA) is presented in this paper. A calibration scheme adopted in this chip to cancel the leakage current due to OFF-state MOS switches tied to the measuring path is also demonstrated.
