单片机编程 1A SIMPLE STEP-DOWN SWITCHING
The TL2575 and TL2575HV represent superior alternatives to popular three-terminal linear regulators. Due totheir high efficiency, the devices significantly reduce the size of the heatsink and, in many cases, no heatsink isrequired. Optimized for use with standard series of inductors available from s ...
模拟电子 提高在噪声环境下的磁卡读写器(MCR)系统
Abstract: Most magnetic read head data sheets do not fully specify the frequency-dependent components andare often vague when specifying other key parameters. In some cases, the specifications of two very similarheads from two different manufacturers might be quite different in terms of parameters ...

Who has never experienced oscillations issues when using an operational amplifier? Opampsare often used in a simple voltage follower configuration. However, this is not the bestconfiguration in terms of capacitive loading and potential risk of oscillations.Capacitive loads have a big impa ...

书籍 Switch Mode Power Supplies
For many years prior to the 1970s, engineers designed and built switch mode
power supplies (SMPSs) using methods based largely on intuitive and exper-
imentally derived techniques. In general, these power supplies were able to
achieve their primary goal of high-efficiency power conversion; unfortu-
...
电源技术 DN464 高效率USB电源管理系统
 
Automotive power systems are unforgiving electronicenvironments. Transients to 90V can occur when thenominal voltage range is 10V to 15V (ISO7637), along withbattery reversal in some cases. It’s fairly straightforwardto build automotive electronics around this system, butincreasingl ...
书籍 The RF in RFID
To a quantum mechanic the whole universe is one godawful big interacting wavefunction ?
but to the rest of us, it’s a world full of separate and distinguishable objects that hurt us
when we kick them. At a few months of age, human children recognize objects, expect
them to be permanent and move con ...
书籍 Essentials+of+Short-Range+Wireless
Over the past ten years there has been a revolution in the devel-
opment and acceptance of mobile products. In that period, cel-
lular telephony and consumer electronics have moved from the
realm of science fiction to everyday reality. Much of that revolu-
tion is unremarkable – we use wireless, in ...
书籍 MultivariableControlSystems
This introductory chapter is devoted to reviewing the fundamental ideas of
control from a multivariable point of view. In some cases, the mathematics
and operations on systems (modelling, pole placement, etc.), as previously
treated in introductory courses and textbooks, convey to the readers an un- ...
