REFERENCE VOLTAGE GENERATOR |
摘要 |
A reference voltage generator including a reference voltage generating unit is provided. The reference voltage generating unit receives a first bias voltage current and a first mirror current and generates a reference voltage. The reference voltage generating unit includes a first metal-oxide-semiconductor (MOS) transistor, a second MOS transistor, a first impedance providing element and a second impedance providing element. The first and the second MOS transistors operate in a sub-threshold region so as to generate a first gate-source voltage and a second gate-source voltage having a negative temperature coefficient. The first impedance providing element is configured to generate a first current having a positive temperature coefficient. The second impedance providing element is configured to generate a first voltage having a negative temperature coefficient at its first terminal. The reference voltage is equal to a sum of the second gate-source voltage and the first voltage. |
