Programmable Voltage Reference |
摘要 |
A programmable voltage reference includes a temperature compensated current source and a voltage reference circuit. The temperature compensated current source includes an output configured to provide a reference current. The voltage reference circuit includes an input coupled to the output of the temperature compensated current source and a reference output. The voltage reference circuit includes a self-cascode metal-oxide semiconductor field-effect transistor structure that includes a first device that is diode-connected and operates in a weak inversion saturation region and a second device that operates in a weak inversion triode region. A length of the second device is selectable. The voltage reference circuit is configured to provide a reference voltage on the reference output based on the reference current.
