A new approach to adding built-in self test (BIST) capabilities to integrated sigma-delta modulation RF transmitters is presented. An area efficient, all-digital building block generates multitone FM stimulus signals without compromising the performance of the RF transmitter itself. The RF signal is demodulated and digitized in a on-chip digital FM discriminator. Both blocks are fully testable ...

Evaluation of Through Silicon Via (TSV) electrical performance is hardly required today to improve heterogeneous 3D chip performance in the frame of a “more than Moore” approach. Accurate modeling of TSV is consequently essential to perform design optimizations and process tuning. This paper proposes a methodology based on RF characterizations and simulations, leading to a frequency dependent a...

This proposed architecture is a single-end to dual-end CMOS RF front-end which is applied for LTE system. This work use Digital IF receiver architecture including current reuse source inductive degeneration LNA and folded-cascode mixer in accord with 3GPP LTE system standard. Since LTE is a communication protocol applied on handheld devices, the demands of circuit designs are based on low power...

Bluetooth is a communications standard targeting shortrange wireless communications with data rates of 1Mb/s at 10m distance. To encourage Canadian universities to pursue this commercially promising standard the Canadian Microelectronics Corporation is providing the intellectual property for a Bluetooth SOC Reference Platform. This platform does not currently include an RF transceiver core. Thi...

RF circuits for multi-GHz frequencies have recently migrated to low-cost digital deep-submicron CMOS processes. Unfortunately, this process environment, which is optimized only for digital logic and SRAM memory, is extremely unfriendly for conventional analog and RF designs. We present fundamental techniques recently developed that transform the RF and analog circuit design complexity to digita...

The analog IC technology, might sound old-fashioned, is still important for the future wireless systems such as 4G cellular phone systems, broadband wireless networkings, and wireless sensor networkings. The analog features and issues of the scaled CMOS transistor, the basic issue and the technology trend for the ADC as an important building block of wires systems, and the feature of the digita...

The paper presents the challenges involved in a system design of a robust reconfigurable RF front-end for navigation and mobile standards. Receiver architecture is chosen from the point of view of inter-system interference and 130nm CMOS process characteristics. System concept covers the implementation of GPS, Galileo, UMTS, GSM and CDMA2000 using a Zero-IF architecture with reconfigurable anal...

ion Scale Properties Nano CMOS 30-100nm Capacitance in CMOS RF MEMS 100-500nm Properties of antenna CNT 10-30 nm Conductance Although these tools have been successful in simulating the behavior of simple-function devices but fails when it goes to more complex areas because the physics developed cannot explain accurately all the properties, also they have not been as successful in simulating the...

Abstract: The effect of using a tuning inductance on the performance of a Gilbert cell-based two level transistor CMOS sub-harmonic mixer is investigated. The tuning inductor used between the RF and LO switching stages causes conversion gain enhancement and noise figure improvement. Additionally, it compensates LO distortion due to the phase mismatch of LO signals in the sub-harmonic mixer. The...

Commercial Applications Solid state and electromagnetic relay switches are being replaced by MEMS switches due to their lower costs and increased application performance. Some of the benefits of MEMS switches include low power consumption, long life cycle, linearity and increased switching speeds. Applications include highspeed digital channel switching in automated test equipment, filter bank ...
