I want to design a circuit mechanism that will amplify the input current by 6 times. The circuit must contain at least 3 MOSFETs, 1 independent source, 1 resistor. I tried but couldn't do it on ltspice. Can someone show me the circuit on ltspice ? thanks.

 

Hi quad,

hello. I did make a circuit using only one MOSFET, but it does not have the features I want, but at least 3 are required, so there is no need to put here. I couldn't understand how to do it.

 

1 independent source

Source of what? LTspice has both current and voltage sources.

Our purpose in the circuit varies depending on whether we increase the voltage or current of the source. In this example, since we will increase the current, it will probably be an independent current source.

 

it will probably be an independent current source

You will need to get that confirmed by whoever set your assignment. The power supply for your circuit is a voltage source. Does that count, or is your 'independent source' something extra?

yes you can use voltage source for power supply.Independent source is not something extra .
