Introduction
In order to process signals, we have to design and implement systems called filters. A
filter is a device that transmits (or rejects) a specific range of frequencies. There are four
basic filter types; low-pass, high-pass, band-pass, and band
Current mirrors
Current mirrors are important blocks in electronics. They are widely used in
several applications and chips, the operational amplifier being one of them.
Current mirrors consist of two branches that are parallel to each other and

The main property/feature of a current source/sink is that the current though the device is
independent of the voltage across it. Figure 1 shows the most basic of current sink. The
