Patent
Monolithically integrated switched capacitor bank using micro electro mechanical system (MEMS) technology
J. L. Julian Tham,James L. Bartlett,Mau-Chung Frank Chang,O. Marcy th Henry,Deepak Mehrotra,Kenneth D. Pedrotti,David R. Pehlke,Charles W. Seabury,Jun J. Yao +8 more
TL;DR: In this paper, a monolithically integrated switched capacitor bank using MEMS technology that is capable of handling GHz signal frequencies in both the RF and millimeter bands while maintaining precise digital selection of capacitor levels over a wide tuning range is presented.
Journal ArticleDOI
Accurate modeling and parameter extraction for MOS transistors valid up to 10 GHz
TL;DR: In this article, the authors presented an accurate modeling and efficient parameter extraction of the small signal equivalent circuit of submicrometer MOS transistors for high-frequency operation, based on a quasi-static approximation which was found to be adequate in the gigahertz range if the extrinsic components are properly modeled.
Patent
Integrated tunable high efficiency power amplifier
James L. Barlett,Mau-Chung Frank Chang,Henry O. Th Marcy,Kenneth D. Pedrotti,David R. Pehlke,Charles W. Seabury,Jun J. Yao,Deepak Mehrotra,Julian J. L. Tham +8 more
TL;DR: In this paper, a tunable reactive device (Cshunt, C-E, E and F) is proposed for power amplifiers with reactive networks, with the reactive devices respective reactance values capable of being adjusted by means of respective control signals.
Patent
Integrated passive transceiver section
J. L. Julian Tham,Deepak Mehrotra,James L. Bartlett,Mau-Chung Frank Chang,O. Marcy th Henry,Kenneth D. Pedrotti,David R. Pehlke,Charles W. Seabury,Jun J. Yao +8 more
TL;DR: In this paper, the passive components of a transceiver, such as transmit/receive switches, antennas, inductors, capacitors and resonators, are integrated together on a common substrate to form an integrated passive transceiver section, which, in combination with other components, provides a highly reliable, low-cost, high performance transceiver.
Patent
Tunable-trimmable micro electro mechanical system (MEMS) capacitor
Mau-Chung Frank Chang,O. Marcy th Henry,Kenneth D. Pedrotti,David R. Pehlke,Charles W. Seabury,Jun J. Yao,Sangtae Park,J. L. Julian Tham,Deepak Mehrotra,James L. Bartlett +9 more
TL;DR: In this paper, a high Q MEMS capacitor that can be continuously tuned with a large tuning ratio or reversibly trimmed using an electrostatic force was presented. But the tuning error was not addressed.
