Claim 0:
1. A bias voltage generating device, comprising:
a first diode-connected transistor pair connected to receive a first voltage, the first diode-connected transistor pair includes a diode-connected p-type transistor and a diode-connected n-type transistor;
a second diode-connected transistor pair connected to receive a second voltage; and
a first transistor pair connected to the first diode-connected transistor pair and the second diode-connected transistor pair, the first transistor pair configured to generate a third voltage in response to the first voltage and the second voltage,
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.
