This lecture delves into the design of inverting rectifiers using operational amplifiers. The instructor explains how to create a function where the output voltage is zero for positive input voltages and positive for negative input voltages. By analyzing the circuit with and without diodes, the lecture demonstrates the behavior of the amplifier in different scenarios. The use of two diodes in the inverting rectifier design is explored, highlighting the advantages of this configuration over a simple rectifier. The impact of the amplifier's slew rate on voltage variations at the output is discussed, along with strategies to mitigate deviations. The lecture concludes by addressing the limitations of non-inverting rectifiers and the importance of stability in amplifier applications.
