A constant current source is provided by a circuit of two metal oxide semiconductor field effect transistors (MOSFET) of the enhancement type having opposite conductivities. One transistor constitutes an input transistor. The other transistor is the output transistor. The drain terminals are connected ...
“Kelvin method” or 4-wire measurement. This involves passing a highly stable current derived from a temperature compensated constant-current source through the unknown resistance, and then using another pair of leads to measure the voltage drop across the resistor, which then gets displayed as a...

摘要: PURPOSE:To obtain a constant gate bias voltage which is not affected by the fluctuation of the supply voltage, by providing Zener diode ZD connected in the opposite direction and MOSFET which operates at the satuaration reagion and on the constant voltage obtained through ZD....
Also not sure of what MOSFET to use. I just choose one that is in TI-TINA.Basically I'm looking for some feedback on anything that I should be careful with or drawback of this design. CurrentLimiter3.PNG (77.5 kB, 1606x639 - viewed 651 times.)...
Circuit below shows a MOSFET amplifier biased by a constant-current source I. Assume that the values of I and RD are such that the MOSFET operates in the saturation region. Find the input resistance and the voltage gain . A、 B、 C、 D、
For Method II in Figure 9d,e, 𝑣𝑝vp and 𝑣𝑠vs are always the same, and the resonant current is in phase with both voltages due to the resonance operation. Moreover, it is a fixed frequency and free-of-control CV stage. In Figure 10, the drain-to-source voltage of switches...
A constant current source (CCS) in electronics is a device/circuit that produces a constant value of current regardless of source voltage or load resistance. Fig. 1 illustrates a simple constant current source (CCS) circuit using a PNP bipolar transistor. ...
