  • In this video we have covered the basic architecture of MOS transistor. The types of MOSFETs and how a MOSFET can act as a switch are explained in detail. Further, the definition of threshold voltage is discussed with proper explanation.

    Answer to the question asked at 24:28 --The one which is connected to higher potential (Vdd) is drain and the one which is connected to lower potential (vss) is source . It is called symmetric because rise time and fall time are equal, device ratio is unity.

    One side is specified as source and other as drain just because of the voltage difference .as we all know that the source is grounded the side which has lower potential is known as source and the side with higher potential is known as drain.

    At 40:48, i think in depletion type n-MOSFET there is a physically implanted channel(as i have read from the books) . It does not have an N-type substrate as you quoted sir. But when there is a channel already present then how does the electric field modulate the channel which is the basic working of a MOSFET.

    What is the most suitable answer for the question asked at 24:32?
    if mos structure is symmetrical then why one region is called source and another drain?

    • @gaganaggarwal7599
      @gaganaggarwal7599 4 роки тому +12

      Because although they seem diagrammatically similar, at high frequency of operation, they do not exhibit the same capacitances (because they are made that way, they source being closer to the bulk). So yeah, sure for DC operation their switching action is symmetrical but not in computer circuits operating at GHz frequencies.

    • @09baher
      @09baher 2 роки тому

      good discussion, most of the circuit analysis, we use the convention current was is based on "holes" so opposite of "electron". So, when we say S-to-D that is the "electron" current, in circuit analysis (textbooks), most of the time we are assuming the convention or "hole" current which so D-to-S current. It can be confusing.
