Low noise amplifier when simulated for system level configuration, the scattering matrix in general and scattering parameters in specific play vital role in performance of low noise amplifier for various frequency bands. In this paper the scattering parameter performance was analyzed for C-band for recent process technologies available for CMOS and BiCMOS for IEEE 802.11 b/g.

This project develops PLL macros that use novel digital architectures to achieve a user configurable optimum balance between phase noise, frequency resolution, frequency switching time, and power consumption. The PLL macros are implemented in SiGe BiCMOS to take advantage of the good phase noise and power consumption attributes. The digital nature of the implementation facilitates easy porting ...

A chip-scale, highly-reconfigurable transmitter and receiver, which hetero-integrates Northrop Grumman’s novel phase-change switch (PCS) technology with commercial SiGe BiCMOS using 3Dstacking has been demonstrated. Further miniaturization and performance improvements are being pursued through fully monolithic integration. The current state of the technology will be discussed followed by a disc...

Continuing advances in silicon integrated circuit technology lead to todays very large scale integrated circuits with several millions of transistors per single chip. High density and low power consumption advantage made CMOS technology to the leading silicon fabrication technology. Over the last decade the demand for higher speed and better analog circuit gave rise to the BiCMOS technology, wh...

We propose a novel 50 Mb/s optical transmitter fabricated in a 0.6 μm BiCMOS technology for automotive applications. The proposed VCSEL driver chip was designed to operate with a single supply voltage ranging from 3.0 V to 5.25 V. A fully integrated feedforward current control circuit is presented to stabilize the optical output power without any external components. The experimental results sh...

Recently digital signal processing has become very popular in video signal processing systems. Analog-toDigital (A/D) converters in this field, namely, video A/D converters, are also popular and have been integrated into mixed-signal system LSIs. Both power consumption and power supply voltage of video A/D converters have been decreasing drastically in recent years [1], [2]. One of the applicat...

A fully differential high-Q bandpass filter that uses lossy integrated inductors is presented. The circuit is implemented in a 0.8 m BiCMOS technology and realizes a center frequency of 750 MHz with a Q-factor that is tunable from 10 to 490 while dissipating 80–100 mW from a single 5 V supply. Since the objective of the prototype was to explore the proposed Qenhancement technique, the dynamic r...
