Claim 14:
15. A bias voltage generating device, comprising:
a reference bias section connected to receive a first voltage and a second voltage, the reference bias section comprising a first diode-connected transistor pair connected to receive the first voltage and a second diode-connected transistor pair connected to receive the second voltage, the first diode-connected transistor pair includes a diode-connected p-type transistor and a diode-connected n-type transistor; and
a driving section connected to the reference bias section, the driving section configured to generate a third voltage in response to the first voltage and the second voltage, the driving section comprising a first transistor pair,
wherein a drain and a gate of the diode-connected p-type transistor of the first diode-connected transistor pair and a drain and a gate of the diode-connected n-type transistor of the first diode-connected transistor pair are connected to a gate of a n-type transistor of the first transistor pair.
