Oscillator is an amplifier with positive feedback. An inverting amplifier is the basic building block of an oscillator. Consider a feedback system as shown in Figure 1. Figure 1. Block diagram of a feedback control system The closed loop transfer function is, (1) The characteristic equation is . For […]
In Cadence, we can pass parameters individually from each instantiated symbol to schematic using Component Description Format(CDF) parameters. Where do I require? Suppose you want to test your design idea, where you require two op-amps with different specifications but want to use same macro model/schematic for both opamps. Suppose you […]
[Could not find the bibliography file(s) An integrated circuit on a die is connected to external world through bond wires. Depending on the packaging or assembly technique we use, the bond wire length changes. The self or mutual inductance of the bond wire is directly proportional to length and have […]
