Patent ID: 7236050

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