Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 1-10 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 1 recites the limitation "… in which a temperature coefficient of the sample-time generator being substantially equal to the temperature coefficient of the first VCO…" in lines 6-8 of Claim 1. There is insufficient antecedent basis for this limitation in the claim. There is no prior disclosure of a “temperature coefficient of the first VCO” before this moment. What is disclosed before this moment is a “temperature coefficient of the sample-time generator”.
Claims 2-10 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph as they further limit Claim 1.
Please make the proper corrections.

Zhang US 2013/0033231 - A cell balancing system includes multiple bypass paths and a battery management circuit. The multiple bypass paths are coupled in parallel to the battery cells. The battery management circuit is coupled to the bypass paths and monitors cell voltages of the battery cells, compares the cell voltages with a first reference voltage for a first stage, enables a bypass path in the first stage if a battery cell in parallel with the bypass path has a cell voltage at the first reference voltage, and compares the cell voltages of the battery cells with a second reference voltage for a second stage if a specified cell voltage in the first stage is at the first reference voltage.
Xue et al. US 2014/0203782 - A battery management system includes detecting circuitry and control circuitry coupled to the detecting circuitry. The detecting circuitry detects cell voltages of battery cells of a battery pack. The control circuitry alternates between a normal state and a charging prohibition state. In the normal state, charging of the battery cells is enabled and the cell voltages increase, and if a voltage of a battery cell of the battery cells exceeds a predetermined overcharge threshold, then the control circuitry transitions to the charging prohibition state. In the charging prohibition state, charging of the battery cells is disabled, and the voltage of the battery cell decreases if at least one cell of the battery cells has a voltage less than a balance threshold.

Each of the battery modules comprises battery cells, balance circuits and a battery management module. The battery management module in each of the battery modules is coupled to the battery cells and for acquiring cell voltages of battery cells. The balance circuits are coupled to the battery cells and for performing balance operation on the battery cells under control of the battery management module. The controller is coupled to the battery modules and for generating a reference signal based on the cell voltages provided by each of the battery modules.
