Abstract
A reference voltage circuit with current buffer including a low voltage reference to output a low voltage, a first resistor-capacitor (RC) filter to filter the low voltage, a buffer circuit to output a current to be used by a load, a second RC filter associated with the load, and a capacitor in parallel with the buffer circuit configured to increase a rise time of the buffer.
