Title: Semiconductor measuring apparatus
Inventor: NOGUCHI TERUO
IPC: G01R31/319
Filed: 1990-02-01
Abstract: PURPOSE:To measure the characteristic of a frequency axis at high speed on the basis of the min. number of data by constituting an integrator of an amplifier, a resistor and a capacitor to make it possible to continuously change cut-off frequency. CONSTITUTION:An integrator is constituted of a capacitor 303, an amplifier 304 and a resistor 305. A switch S2 is turned ON before a signal to be measured is inputted to initialize the integrator and, thereafter, a switch S1 is turned ON to integrate the signal to be measured and, when the switch S1 is turned OFF after a time tw, the output of the integrator is held and, therefore, said output is quantified by an ADC 103 and a digital value is stored in an MEM 104 and Fourier transform is performed to the digital value to perform the analysis of the characteristic on a frequency axis by a CPU 106. In this case, the cut-off frequency fci of a low frequency filter due to the integrator is 1/(2xtw). Therefore, when tw is set to 1/(2xfm)(fm : the frequency of the signal to be measured), the integrator acts as the low frequency filter of cut-off frequency fm and functions as the optimum anti-aliasing filter. Therefore, the characteristic of a frequency axis can be measured on the basis of the min, number of data at high speed.
