ABSTRACT:
A current mirror comprising: a first current source; a first n-channel MOS transistor having a drain and a gate coupled to said current source and a source coupled to ground; a second n-channel MOS transistor having a drain, a gate coupled to said drain and said gate of said first n-channel MOS transistor, and a source coupled to ground; a third n-channel MOS transistor having a source coupled to said drain of said second n-channel MOS transistor, a gate, and a drain comprising an output-current node; a second current source; a p-channel MOS transistor having a drain coupled to ground, a source coupled to said second current source and said gate of said third n-channel MOS transistor, and a gate coupled to said drain and said gate of said first n-channel MOS transistor.
