Abstract
An apparatus and method for a voltage reference circuit with improved precision. The voltage reference circuit utilizes threshold voltage difference between a pair of MOSFETs. A voltage reference circuit between a power supply node and a ground node and configured for generating a reference voltage, includes a first current mirror with a first NMOS transistor and a second NMOS transistor wherein said first NMOS transistor threshold voltage is not equal to said second NMOS transistor threshold voltage, a second current mirror with a first PMOS transistor, a second and third PMOS transistor configured to be coupled to said power supply node, a current source configured to be provide current to said second current mirror, an amplifier configured with a first and second input configured to be connected to the drains of said first NMOS transistor and said second NMOS transistor and, a feedback loop configured to be the output of said amplifier.
