Ninth class, An architect's job

As during the former class we learnt several types of circuits which involve the use of the OA, now we have to go a step forward through our journey to master the linear circuits, and it is to work as architects. Namely, we will focus on the modular design of circuits through the use of functional blocks. 

So, basically, it consists on getting a specific output signal function of one or more input signals and try to design a circuit which fits the function given. We reviewed all the circuits used previously and organized something like a 'catalog' of modular blocks. Examples of them are: the non-inversor circuit (Vo = K * Vin), the inversor circuit (Vo = -Vin), the subtractor circuit (Vo = V1 - V2), the tension follower (it 'reads' the signal given from an past circuit without altering it) and the derivator and integrator circuits. In my humble opinion, I think it is a big step for me, as I feel I can now achieve new goals and create the circuits myself. 

During the last part of the class, we introduced a new function for the OA: the comparator, a very useful property of the OA which opens a new door of possibilities, as we will see at my next blog entry.
