In our earlier discussions we observed that the N-channel Enhancement-mode MOSFET (e-MOSFET) operates effectively when supplied with a positive input voltage. This particular type of MOSFET boasts an exceptionally high input resistance—approaching infinity. This facilitates its use as a switch. This characteristic allows us to interface the MOSFET seamlessly with virtually any logic gate or […]

How to Use Transistors (BJTs) as ON/OFF Switch
In applications where we use a transistor or a BJT to amplify an AC signal, it becomes crucial to set its base bias voltage correctly. This allows the transistor to sit comfortably in its “active” zone, which means we are working within the linear range of the output characteristic curves. The exciting part is that […]
