How should I correct this NMOS static inverter?
So in my notebook I have this circuit scheme for a NMOS static inverter:
Vi is the input
Vo is the output
VDD is the voltage source
It is obvious that the M2 MOSFET will never turn on. Is the circuit ...

Water level indicator using CMOS inverter
I want to build the below circuit. The circuit has three levels to indicate water. low->o/p LED. Medium->O/P LED. High->O/P LED + Buzzer. Each level has two types of MOSFET; they work as CMOS ...

How is common source NMOS stage with active current load realized in practice?
In a well known book about CMOS circuit design (Design of Analog CMOS Integrated Circuits) I found this example about a cascode stage with current source load.
The basic idea is, to replace the drain ...

Separating power ground from control ground to exceed NMOS threshold voltage
I'm a novice circuit designer looking to create a high voltage source follower NMOS circuit. I originally planned to use a Teensy digital I/O pin as the gate control signal, so when the Teensy ...

Can't turn on NMOS when using 1M pull-down resistor on gate
I am using ATmegA328P MCU to control ignitors which need about 500 mA current to work. To provide such current, I use AO3400A N-MOS to control the ignitors. In early design, I didn't use pull-down ...

Design a circuit to determine NMOS parameters
I am studying electronics independently, so this question is perhaps obvious for an engineering student.
I know that, for the ALD1106 MOSFET, we can assume a typical \$V_t = 0.7 V\$. How could I ...

Trying to have NMOSs in parallel while passing current through only one at a time
If I wanted to have a bias current I1 going through M1 or M2 and I want M1 to alternate between on off (M1 on/M2 off, M1 off/M2 on) would this work? I simulated this with spice and for the first ...

Can I use TXB0104B bidirectional level shifters on the Intel 8085 NMOS CPU buses?
I want to connect an old Intel 8085 CPU to an FPGA board. The basic issue is that the 8085 works at 5V while the FPGA will not accept any voltage avobe 3.3V so I decided to use the TXB0104 / TXB0108 ...
