We demonstrate, using a foundry-based 65nm bulk technology, mmWave CMOS VCOs in the range of 38GHz and 77GHz with highest reported continuous tuning range (14%&#x2013;25%), competitive phase noise (&#x2212;88dBc/Hz at 1MHz offset at 77GHz), and high P<inf>out</inf> (6dBm at 77GHz) needed to readily integrate with CMOS PA and to tolerate PVT variations.

paper reports a LNA and a PA for IEEE802.15 WAPN application in a 90-nm LP (low power) 1P6M CMOS technology. The LNA has a 13-dB peak gain and a 7-dB NF and the PA has a 9.8-dB gain and a +11.2-dBm saturated output power. Both LNA and PA have achieved input and output matching bandwidths exceeding 10 GHz, while the reflection coefficient (|S<sub>11</sub>|,(More)
This brief presents a new, simple method of measuring the generation lifetime in silicon-on-insulator (SOI )MOSFET’s. Lifetime is extracted from the transient characteristics of MOSFET subthreshold current. Using this technique, generation lifetime was mapped across finished Separation by IMplantation of OXygen (SIMOX) wafers and Bonded and Etchedback SOI(More)
We propose a new motor concept, which is particularly suitable for space missions. The motor made of shape memory alloys can be actuated by sunlight directly. The principle for the operation is similar to the shape memory alloy based heat engines, which were quite popular some years ago. However, unlike those old heat engines, which are driven by hot/cold(More)
Radio frequency (RF) and analog/mixed-signal (AMS) integrated circuits (ICs) are key enabling components for mobile and wireless communications and their advancements continue to drive the growth of the related semiconductor market. The circuit and technology requirements for RF and AMS ICs in mobile and wireless communications are quite different in(More)
On-chip integration of artificial (slow-wave) transmission lines (ATL) formed by periodic loading of microstrip lines with MIM capacitors is demonstrated, for the first time, using 0.18&#x00B5;m SiGe:C BiCMOS. We demonstrate 2&#x00D7; length-reduction of &#x03BB;/4-stub RF choke and filters at 38GHz and at 77GHz. Due to the extensive use of TLs in mmWave(More)
