A significant team project is required in this course.Ĭomponent(s): Lecture 3 hours per week Tutorial 2 hours per week Notes:Īll written documentation must follow the Concordia Form and Style guide. The students are also introduced to the basic principles of mechanics including the description of translational motion, rotational motion, forces and moments, work and energy, and they build a mechanical prototype to which the electronics and software are then added. Students present their design and demonstrate that their design works in a competition at the end of the term. Students work in teams and each team designs and builds a prototype defined by the Department. The following courses must be completed previously: ENCS 282 ENGR 213, ENGR 233.ĭescription: The introductory team design project introduces students to teamwork, project management, engineering design for a complex problem, technical writing and technical presentation in a team environment.

The resistors R1 and R2 do not play any role since the op-amp inputs have high resistance and should be removed.The following course must be completed previously or concurrently: MATH 204 (Cegep Mathematics 105). The op-amp non-inverting amplifier is another example of this unique feature where the attenuating voltage divider is made to act as an "amplifying voltage divider". This is a fundamental property of negative feedback systems. and it acts as the dual voltage-to-current converter (I = V/R). It is interesting to see that both resistors Rs and R3 act as current-to-voltage converters (V = I.R) but the function of R3 is "reversed" by the negative feedback. i.e., perfect voltage-to-current converter (current sink). Thus the combination of the op-amp and emitter-follower can be considered as a perfect voltage follower working on the resistive load R3. For this purpose, the op amp "lifts" its output voltage with VBE so the emitter voltage is equal to the input voltage (across Rs). The clever trick of this circuit solution is that the emitter follower (Q1) is put in the feedback loop and the op-amp compensates the transistor base-emitter voltage VBE. So IOUT.R3 = IIN.Rs -> IOUT = IN.Rs/R3 = IIN/2000, i.e., the circuit is a current attenuator. Simply speaking, the input current creates a voltage drop Vs = IIN.Rs across Rs and the op-amp follower copy this voltage across R3 by the help of the output (collector) current IOUT. current attenuator or, if the output current is equal to the input one, the so-called current mirror. This circuit consists of two cascaded dual circuits - current-to-voltage converter (Rs) and voltage-to-current converter (the op-amp, Q1 and R3).
