Please make the following circuits on PSPICE and do the simulations according to the specifications*

The goal of this assignment is to not use DC voltage, but to amplify the signal and then check the signal that passed the low pass filter.

Circuit 1. The rectification circuit:

• Construct a rectification circuit using a diode and show the result of converting the AC voltage to a DC voltage.

• The input signal uses Vsin.

• The offset voltage should be 0, the amplitude should be 9 volts, and the frequency should be 1 kHz. (Voff=0, Amplitude=9V, Frequency=1kHz).

---------------------------

Circuit 2. The amplifier circuit:

• The second circuit is the amplifier circuit which uses the rectified voltage in the first rectification circuit as Vcc.

• Input AC has 0.2V amplitude and requires the output waveform to be amplified by 10 times or more

• It may take some time to stabilize the output signal because it uses a rectified voltage rather than a complete DC voltage. Therefore, please simulate within a sufficient time range.

• You can also use BJT to make the amplifier freely

----------------------------

Circuit 3. Low pass filter:

• The third circuit is the low pass filter. Low pass filter is a circuit that outputs signals below the cut- off frequency and blocks signals above the cut- off frequency.

• The Low pass filter allows you to set the cut-off frequency according to the R and C values.

• you must design with a cut-off frequency of 2kHz. You can measure the dB value by changing the settings of the graph in the simulations of the PSPICE
