Title: Measuring field effect transistor
Inventor: SUZUKI KOUICHI
IPC: G01R31/26
Filed: 1981-02-27
Abstract: PURPOSE:To obtain a mutual conductance gm and parasitic resistance Rs by utilizing the fact that, when n pieces of FET's are connected in parallel and the gate width is multiplied by n, the ideal mutual conductance is n<1/2> and the parasitic resistance Rs on the source side becomes its 1/n. CONSTITUTION:Utilizing the fact that, when n pieces of FET's with equivalent characteristics are connected in parallel, the mutual conductance gm, n (gm being ideal mutual conductance) is expressed by Formula, mutual conductances of gm, 1, gm, 2 of n, for instance a single FET(n=1) and two pieces of FET's(n=2) connected in parallel are measured. Then the parasitic resistance Rs and mutual conductance gm can be easily sought by calculation. Mutual conductances are,  however, to be measured, as will be seen in actual calculation, with extremely  high accuracy, but when given gm, Rs are used as concentrated constant number equivalent value parameter, noise characteristics and high frequency characteristics display very excellent match with actually measured values.

Abstract: PURPOSE:To obtain the titled device which can control the temperature of semiconductor elements easily with high accuracy and has low manufacturing cost, by a method wherein a block heat sink with mounted semiconductor elements is partly provided with a temperature detection element and a temperature control element. CONSTITUTION:A temperature detection element 4 continuously detects the temperature of each semiconductor element during action via heat sink 2 provided with semiconductor elements and sends the detected value to a temperature detection circuit 8. A detection signal is emitted out of this circuit 8 on the basis of the detected value, and this signal is sent to a comparator 10 along with the reference signal, preset at a fixed value, which is emitted out of a temperature reference signal generation circuit 9. The comparator 10 compares the detection signal with the reference signal. When the temperature of the semiconductor element shown by the detection signal goes above a desired temperature of the element shown by the reference signal, then the signal which sets a temperature control element drive circuit 11 in action is emitted out of the comparator. Therefore, an electronic cooling element 5 is driven by the drive circuit, and all the semiconductor elements 1A, 1B, and 2C are cooled at the same time via heat sink 2.
