Claim 12:
13. The IC of claim 10, wherein
the fourth series of n-type HEMTs comprises:
a first enhancement-mode n-type HEMT, a fourth node, and a depletion-mode n-type HEMT coupled between the power supply node and the third node; and
a second enhancement-mode n-type HEMT coupled between the third node and the power supply reference node,

each of the first enhancement-mode n-type HEMT and the depletion-mode n-type HEMT is configured as a diode,
the second enhancement-mode n-type HEMT comprises a gate coupled to the third node, and
the circuit further comprises a capacitive device coupled between the fourth node and the second output terminal.
