Multi-Level Amplification - A New Architectural Approach

Date : 8 February 2006 (Wednesday)

Time : 1 to 2 pm

Venue : LT 5

Speaker : Mr Herbie Kirn, Founder and CTO, Jam Technologies (http://www.jam-tech.com)

Abstract

Classic digital Class D architectures remain reliant on averaging techniques in lieu of high instantaneous resolution capability. A novel high-definition amplifier architecture is presented which provides unprecedented resolution and dynamic range, unaided by feedback of any kind.

Biography

Herbie is founder and CTO of JAM. He invented and patented the JAM core technology for digital audio amplifier semiconductors as well as several key related technologies, yielding 18 issued patents and an additional 22 pending/provisional patent applications.

Previously, Herbie was an electrical engineering contractor to Chrysler, Ford and GM, and was responsible for design and development of electronic controller architectures and real-time operating systems for Chrysler concept vehicles. He invented and patented an engine controller architecture which cost-reduced CPU peripheral silicon costs by 4-8x, and he designed the Chrysler real-time operating system for vehicular controllers.

At Coy Laboratory Products, Herbie was Chief Engineer of a medical equipment manufacturing firm, responsible for R & D as well as production. He became responsible for full company operation, and doubled company sales in his last year there.

Herbie is an accomplished musician and expert in psycho-acoustics, both of which are material factors in the success of his amplifier designs for JAM.

Herbie studied in the Honors Curriculum at Fort Hays Kansas State College and trained under tutelage from the Juilliard School of Music, followed by independent study in psycho-acoustics, digital/analog signal processing, communications, high-power switching, and hardware/software architectures.
