The paper, "A Low-Power High-PSRR Clock-Free Current-Controlled Class-D Audio Amplifier," was written by Dr. Edgar Sánchez-Sinencio, with J. Torres, A. Colli-Menchi and M.A. Rojas-Gonzalez. It not only is in the top four most-accessed papers in JSSC, but it also is the 52nd most-accessed publication for all IEEE publications in July. Earlier this year Sánchez-Sinencio and his former student, Dr. Heng Zhang, had another IEEE top 10 downloaded paper in IEEE Transactions on Circuits and Systems I: Regular Papers.

The recent paper introduces a low-power, high-PSRR, clock-free, current-controlled class-D audio power amplifier. The proposed audio amplifier utilizes integral sliding mode control (ISMC) to ensure robust operation and to minimize the steady-state error. The proposed amplifier achieves up to 82 dB of power supply rejection ratio (PSRR), more than 90 dB of signal-to-noise (SNR) ratio over the entire audio band, and total harmonic distortion plus noise (THD+N) as low as 0.02 percent.

Sánchez-Sinencio, the TI Jack Kilby Chair Professor, has research interests in the areas of continuous-time integrated circuits, analog built-in testing, low-voltage/low-power mixed signal circuits and RF communication circuits. He leads the analog and mixed-signal group and is director of the TEES Analog and Mixed- Signal Center.

He is a Fellow of the IEEE. Among his numerous awards are the IEEE Circuits and Systems (CAS) Darlington Award, the IEEE CAS Outstanding Young Author Award (with graduate student Alex Reyes) and the IEEE CAS Guillemin- Cauer Award for his work on cellular networks. He also received a Texas Senate Proclamation for outstanding accomplishments in recognition of his research. INAOE awarded him its first honorary doctorate in 1995.
