Notorious analog engineer Bob Pease died five Saturday, Bob had come to the service from years ago, on June 18, 2011. His passing was his office at National Semiconductor, now all the more tragic since he died driving home Texas Instruments. My buddy has a from a remembrance for fellow analog saying, "Everyone wants to be somebody, no great Jim Williams. Although it was a one wants to become somebody." 1 of 12 9/2/2018 6:49 PM 1 of 12 Bob Pease, analog guru, died 5 years ago - Media Rako.com/Media 2 of 12 Bob's being the most famous analog designer After coming to National Semi, Bob learned was the result of his hard work becoming a analog IC design, back in the days ofhand-cut brilliant engineer, with a passion for helping Rubylith masks. There was no Spice simulator others. Fran Hoffart, retired Linear Tech apps back then, and Pease had deep ridicule for engineer and former colleague recalls, "Citing a engineers that relied on computer simulations, need for educating fellow engineers in the insteadof thinking through the problem and design of bandgap references, Bob anointed making some quickback-of-envelope himself 'The Czar of Bandgaps,' complete with calculations. He accepted that Spice was useful a quasi-military suit with a sword and a especially for inexperienced engineers, but was necklace made from metal TO-3 packages." He concerned thatengineers were substituting would help any engineer with a problem, even computer smarts for real smarts. -

Department of Informatics Networks and Distributed Systems (ND) group INF 3190 Wireless Communications Özgü Alay [email protected] Simula Research Laboratory Outline • Brief history of wireless • What is wireless communication? • Bottom-down approach – Physical layer : how can we transmit signals in air? – Link layer : multiple access – Wireless impact higher layers? • Wireless Systems – Mobile Broadband Networks – Wifi – Sensor Networks, Adhoc Networks 2 Wireless History • James C Maxwell ( 1831- 1879) laying the theoretical foundation for EM fields with his famous equations • Heinrich Hertz (1857- 1894 ) was the first to demonstrate the wave character of electrical transmission through space (1886). (Note Today the unit Hz reminds us of this discovery). • Radio invented in the 1880s by Marconi • The 1st radio broadcast took place in 1906 when Reginald A Fessenden transmitted voice and music for Christmas. • The invention of electronic vacuum tube in 1906 by Lee De Forest (1873-1961) & Robert Von Lieben (1878 – 1913) helped to reduce the size of sender and receiver . 3 Wireless History cont… • In 1915 , the first wireless voice transmission was set up between New York and San Francisco • The 1st commercial radio station started in 1920 – Note Sender & Receiver still needed huge antennas due to high transmission power. • In 1926, the first telephone in a train was available on the Berlin – Hamburg line • 1928 was the year of many field trials for TV broadcasting. John L Baird ( 1888 – 1946 ) transmitted TV across Atlantic and demonstrated color TV 4 Wireless History cont … • Invention of FM in 1933 by Edwin H Armstrong [ 1890 - 1954 ] . • 1946, Public Mobile in 25 US cities, high power transmitter on large tower. -
Analog Father.Indd
The Father of Analog Integrated Circuits: Robert J. Widlar From: Tales of the Continuum: A Subsampled History of Analog Circuits By Thomas H. Lee, Center for Integrated Systems, Stanford University At a time when even discrete solid-state op-amps had not yet succeeded in displacing their vacuum tube coun- terparts, and the very value of the integrated circuit idea was still a legitimate topic of debate, Bob Widlar (“wide-lar”) almost single-handedly established the discipline of analog IC design. After receiving his bach- elor’s degree in 1962 from the University of Colorado at Boulder, he took a job with Ball Brothers Research, where his virtuosity at circuit design attracted the attention of engineers at one of their components suppliers. Despite the breach in protocol inherent in aggressively recruiting a customer’s key employee, Fairchild induced Widlar to leave Ball in late 1963. In an amazing debut, abetted by Dave Talbert’s brilliant process engineering, Widlar was able to put the world’s first integrated circuit op-amp into production by 1964. Development of the μA702, as Fairchild called it, proceeded despite a general lack of enthusiasm for the project at the company. The Fairchild μA702 Like the K2-W, this op-amp consists of two primary voltage gain stages (Figure 2). As in most differential designs, there is the problem of how to convert to a single-ended output without sacrificing half of the gain (the K2-W simply makes that sacrifice). Here the young Widlar solves this problem with a circuit that presages his later use of current-mirror loads. -
