Voltage References and Current Sources
A voltage reference is an external source that provides a constant voltage supply to the circuit. It is used to maintain a specific voltage level within the circuit.
A current source is an external device that delivers a constant current to the circuit. It is used to maintain a specific current flow.
Voltage References
There are two main types of voltage references:
Fixed voltage references are provided by the manufacturer of the CMOS chip.
External voltage references are connected to the circuit using an external power supply.
Current Sources
There are two main types of current sources:
Fixed current sources are provided by the manufacturer of the CMOS chip.
External current sources are connected to the circuit using an external power supply.
Voltage references and current sources are essential components in CMOS analog IC design. They allow the designer to specify the desired voltage and current levels and ensure that these values are met throughout the circuit
