Q. Common-Drain JFET Amplifier?
Figure (a) shows a CD JFET amplifier in which resistors R1, R2, and RSS are selected by the bias design, and capacitors CG and CS are chosen to be large enough to act as short circuits at frequencies in the band of interest (known as the midband). Figure (b) gives its small-signal ac equivalent circuit. Analysis of this circuit yields
In many cases Av1 = 1 and vL = v1; that is to say the load voltage "follows" the input. Hence a CD amplifier is often known as a source follower, which becomes an excellent buffer to couple a high-resistance source to a low-resistance load with nearly no loss in signal voltage. The current gain, however, can be very large, leading to significant power gain.
A 450 ns EPROM won't work directly with a 5MHz 8088.Why? Explain. While the 8088 is operated along with a 5 MHz clock, it permits 460 ns for the memory to access data. Due to t
