Resident of Sunnyvale
Thomas Frederiksen died peacefully in his home on August 24th, 2015. He was 83 years of age.
Thomas was born on April 29, 1933 in Los Angeles, CA to his parents, Frederic Christian Frederiken and Mary Riddle MeKeown.

Meanwhile, he attended and graduated from Cal Poly San Luis Obispo in 1957 with a BS degree in Electrical Engineering.
During his career Thomas made major contributions to Integrated Circuit design at Motorola, Hughes Aircraft and National Semiconductor.

During semi-retirement he traveled domestically delivering seminars on his methodology of "Intuitive" IC Design and served as Expert Witness in related Industry Patent litigations. He was considered by his peers to be one of the more creative analog chip designers of his time. He was also known as a great mentor and teacher to young circuit designers.

Tom was definitely the most creative and prolific engineers that I ever worked for. His sense of humor and kindly disposition will never be for gotten for those who new him.He was above all the finest human being that I have ever known.

I have four of Tom's famous "Intuitive" Circuit Design books and have enjoyed them very much over the years. So sad. R.I.P.

I considered Tom one of the best in our profession. As a FAE in Boston, and prior to that Central Applications inside NSC, enjoyed talking to Tom and attending his seminar presentations. Also had the opportunity to lunch with him and James Moyer on more than one occasion. I will miss him, a consummate engineer in anyone's playbook.

Regards, Dana.
