摘要： Sampling high frequency input analog signals and conversion to digital output signals accomplished using many analog-to- digital converters and distpbuted sampling system - combination allowing conventional device processing e g 0.18 micron silicon, and providing accurate sampling of very high frequency signals. Distributed sampling system provides multiple samplings of input using multiple ADCs collecting samplings, each offset by a fixed amount of time from the most recent. Each ADC has a designated CPU to obtain sufficient data transfer capabilities. Samplings from ADCs are a sepes of digital output values, possibly the result of samplings at the same or different frequencies. Distributed sampling systems include elongated trace patterns series-connected, inverter pairs series-connected, specific permittivity material device, and sequencer/multiplier. Another sampling system includes vanable-sized aperture window, width of sample pulse narrowed through vapable clock mechanism producing faster sampling rates. Vanable-sized aperture window system can be used solely, or in combination with others.

摘要： A novel a method for determining the internal operation of an integrated circuit (IC) includes measuring electromagnetic (EM) emissions from the integrated circuit chip and analyzing the EM emissions. In a particular method, the EM emissions from the IC are measured using an RF close end probe. In a particular method, the electromagnetic emissions are measured with the IC configured in various ways. In the normal operating mode, the emissions are measured while the IC is provided with power and any external clock signal(s). After measuring the emissions of the IC in normal operating mode, the IC is reconfigured by disabling the external clock signal(s) to the IC and remeasuring the emissions. The external clock signal is disabled by disconnecting the power to the IC, disabling the external clock signal, and then reconnecting power to the IC. In yet a third test mode, the external clock signal is reenabled while power continues to be supplied to the IC. Information about the presence and/or proper functioning of internal clocks of the IC can be determined by analyzing the spectral scan data obtained in one or more of the three test modes.
