Comparator circuit and mobile device

A reference signal generator circuit can be configured to provide a temperature-compensated voltage reference signal at an output node. The reference signal generator can include a diode-connected first FET device coupled between a supply node and the output node, and a flipped-gate transistor coupled between the output node and a reference node. The reference signal generator can include a bias current source configured to provide a bias current to the output node to adjust a current density in the flipped-gate transistor relative to a current density in the first transistor.
