DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claim(s) 1-5, 9 and 11-18 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by [Ridgers et al (Fig. 2); 9,548,701].
Regarding claims 1, 11, 12 and 18, Ridgers et al discloses an amplifier circuit comprising a power amplifier (Q1), an active bias circuit (5, 1) coupled to the power amplifier (Q1) and the active bias circuit (5, 1) comprising a heat-sensitive element (Q2, R3), a droop circuit (15) coupled to the heat-sensitive element (Q2, R3), wherein the droop circuit (15) comprising a current mirror (M1, M2) configured to draw current responsive to changes in the heat-sensitive element (Q2, R3) and generate a trigger signal (the signal generating at the drain terminal of M1), and a correction circuit (Q3) coupled to the power amplifier (Q1) and the droop circuit (15) and configured to receive the trigger signal (the signal generating at the drain terminal of M1) and responsive to receipt of the trigger signal and provide a thermal droop correction to the power amplifier (Q1).
Regarding claim 2, wherein the heat-sensitive element (Q2, R3) comprises a transistor (Q2).
Regarding claims 3 and 13, wherein the transistor (Q2) comprises a heterojunction bipolar transistor.
Regarding claims 4, 16 and 17, wherein the correction circuit (Q3) comprises a variable gain amplifier.
Regarding claims 5, 14 and 15, wherein the correction circuit (Q3) comprises an attenuator (resistance in Q3).
Regarding claim 9, wherein the current mirror (M1, M2) comprises two transistors.
Allowable Subject Matter
Claims 6-8 and 10 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
