TP Electronics

Apply all the concepts covered in the electronics course (module PC6ELECT) by building simple electronic assemblies and characterizing them.
Use the instrumentation and components provided (oscilloscope, generator, operational amplifiers, transistors)
Measure fundamental quantities: gain, phase shift, cutoff frequency, operating point.

The S6 electronics course

Introduction to measuring devices

Draw Black and Nyquist Bode diagrams of first- and second-order circuits.
Use of the oscilloscope: measurement of gains, phase shifts, time constants, cutoff frequencies

The operational amplifier and its limitations

Study of low-pass, band-pass and high-pass filters. Integrator and differentiator behavior.
Demonstrate non-linear operation of the AO at high frequencies, using inverting and non-inverting setups. Measurement of the slew rate of an operational amplifier.

Active filtering of noisy signals

Study of a 5th-order Butterworth filter.

The bipolar transistor as a common emitter

Static (operating point) and dynamic study of two NPN bipolar transistor amplifier circuits: gain, maximum output excursion, measurements to determine hybrid parameters, cutoff frequency.

The field-effect transistor

Dynamic study: gain measurement of amplifier circuits
Definition of an operating point
Reading and plotting of the static characteristics of a field-effect transistor.

Lock-in or synchronous detection

Creation of a noisy signal and extraction of the useful signal from this noisy signal using a simple synchronous detection circuit based on a double analog switch.
