This paper presents a 3.1 - 10.6 GHz ultra-wideband transmitter/receiver chipset for non-coherent communication and localization applications. Its fully differential topology fits promising balanced UWB antennas, and eases ...

A BiCMOS embedded RF-MEMS switch module is demonstrated. The module consists of four main blocks: 1) RF-MEMS switch technology, 2) Switch models for design-kit implementation, 3) High Voltage (HV) generation and digital ...

In this letter, a 60 to 77 GHz switchable low-noise amplifier is presented. The IC is realized in a radio frequency microelectro-mechanical systems embedded 0.25 µm SiGe-C BiCMOS technology. Measured results show that the ...

In this paper a compact and low-power IR-UWB transmitter is presented. The transmitter is based on a cross-coupled LC oscillator core which is transiently turned on and off by current spikes generated on-chip. A simple ...

In this letter, the authors present the design, analysis and comparison of a series of dynamic frequency dividers. These dividers, each consisting of a Gilbert cell mixer core, a transimpedance amplifier and an emitter-follower ...

The introduction of radio frequency micro-electro-mechanical systems (RFMEMS) as a monolithic option into state-of-the-art Si/SiGe BiCMOS foundry processes has paved the way for single chip radio frequency microsystems at ...

Multi-nodal spectrum sensing is a promising approach to robust cognitive radio networks, which provides increased adaptability to database-anchored sharing approaches. Yet its commercially viable implementation requires ...

A U-band VCO and a V-band push-push frequency doubler are designed in a 0.25 mym SiGe:C BiCMOS technology. The VCO oscillates from 48 GHz to 55 GHz, with an output power of around - 1 dBm and a phase noise of - 84 dBc/Hz ...

This article presented the possibilities of making microwave and mm-wave ICs more intelligent through a combination of established Si/SiGe BiCMOS technologies, which allow for complex ICs combining a multitude of high-speed ...

This paper presents a 64-84 GHz phase-locked loop (PLL) realized in a low-cost 80-GHz HBT technology. The circuit consists of a wide tuning-range voltage-controlled oscillator, a push-push frequency doubler, a divide-by-32 ...
