In the following circuit find V1 and I1. (𝑉! = 4 𝑉 and 𝑉"# = 0.7 𝑉)
Design a diode waveform shaping circuit that would have the below transfer function.
The circuits (a) and (b) shown below are connected as follows:
The two input terminals are tied together, and the two output terminals are tied together.
a) Find, sketch and label the transfer function. (Assume 𝑉"# = 0.7 𝑉).
b) Draw the output voltage waveform if 𝑣$ (𝑡) = 2 sin(𝜔𝑡). No need for labeling the time
Show your work.
Design a diode circuit to feed a 1 𝑘Ω load with limiting voltage levels of ±4.4 𝑉. In the
nonlimiting region, the voltage gain should be at least 0.94 V/V.
Plot the transfer function of the following full-wave rectifier. Find 𝑣% for different ranges of 𝑣$
and plot a graph that shows the relationship between 𝑣$ and 𝑣% .
In the circuit below, 𝑣$ (𝑡) = 10 sin(𝜔𝑡) where 𝜔 = 1000 𝑟𝑎𝑑/𝑠, Assume 𝑉"# = 0.7 𝑉 and
𝑣% (0) = 0 𝑉. Calculate and plot two 𝑣% (𝑡) for 0 ≤ 𝑡 ≤ 5 𝑚𝑠.
