MOSFET small-signal model and equivalent circuit
As we discussed before, the output voltage for the MOSFET amplifier is non-linear towards the input voltage: vout=VS-K(vDS-VTh)22RL. Figure 1 shows the MOSFET amplifier…
Introduction into semiconductor memory
Memory is a very important part of a computer that stores programs and data. It can be classified as non-volatile and volatile. First of…
MOSFET amplifier basics
Besides the resistive function, MOSFETs can also perform an amplification function. Let’s consider how we can obtain the amplification function from a MOSFET. Figure…
