Abstract:
A current generator circuit having an output for providing a reference current comprising:a first reference transistor of a first type having a gate coupled for receiving a reference voltage, a drain, and a source coupled for receiving a first power supply voltage; a second reference transistor of said first type having a gate coupled for receiving said reference voltage, a drain, and a source coupled for receiving said first power supply voltage; a bias transistor of a second type having a gate coupled to said drain of said first reference transistor, a drain coupled to said drain of said second reference transistor, and a source coupled for receiving a second power supply voltage; and a buffer transistor of said first type having a gate coupled to said drain of said second reference transistor, a drain coupled to the output of the current generator circuit, and a source coupled to said drain of said first reference transistor.
