DESCRIPTION
The Texas Instruments MSP430 family of ultra-low-power microcontrollers consists of several devices featuring
different sets of peripherals targeted for various applications. The architecture, combined with five low-power
modes, is optimized to achieve extended battery life in portable m ...
The current methods of communications are becoming less relevant under
today’s growing demand for and reliance on constant connectivity. Of
decreasing relevance are the models of a single radio to perform a single
task. The expansion of wireless access points among coffee shops, airports,
malls, an ...
Mobile wireless communications are in constant evolution due to the continu-
ously increasing requirements and expectations of both users and operators.
Mass multimedia* services have been for a long time expected to generate a large
amount of data traffic in future wireless networks [1]. Mass multi ...
Since the advent of optical communications, a great technological effort has
been devoted to the exploitation of the huge bandwidth of optical fibers. Start-
ing from a few Mb/s single channel systems, a fast and constant technological
development has led to the actual 10 Gb/s per channel dense wave ...
The idea for this book was born during one of my project-related trips to the beautiful city
of Hangzhou in China, where in the role of Chief Architect I had to guide a team of very
young, very smart and extremely dedicated software developers and verification engineers.
Soon it became clear that as ...
Wireless communications has become a field of enormous scientific and economic interest. Recent
success stories include 2G and 3G cellular voice and data services (e.g., GSM and UMTS), wireless
local area networks (WiFi/IEEE 802.11x), wireless broadband access (WiMAX/IEEE 802.16x), and
digital broad ...
Sound is simply an airborne version of vibration. The air which carries sound is a mixture
of gases. In gases, the molecules contain so much energy that they break free from
their neighbors and rush around at high speed. As Figure 1.1(a) shows, the innumerable
elastic collisions of these high-speed ...
This design uses Common-Emitter Amplifier (Class A) with 2N3904 Bipolar Junction Transistor.
Use “Voltage Divider Biasing” to reduce the effects of varying β (= ic / ib) (by holding the Base voltage constant)
Base Voltage (Vb) = Vcc * [R2 / (R1 + R2)]
Use Coupling ...
The PW5410B is a low noise, constant frequency (1.2MHz) switched capacitor voltage doubler. Itproduces a regulated output voltage from 1.8V to 5V input with up to 100mA of output current. Lowexternal parts count (one flying capacitor and two small bypass capacitors at VIN and VOUT) makethe PW5410B i ...
