在无线通信系统全面进入3G并开始迈向 4G的过程中，使用数字预失真技术（Digital Pre-distortion，以下简称DPD）对发射机的功放进行线性化是一门关键技术。功率放大器是通信系统中影响系统性能和覆盖范围的关键部件，非线性是功放的固有特性。非线性会引起频谱增长(spectral re-growth)，从而造成邻道干扰，使带外杂散达不到 ...

  Most circuit designers are familiar with diode dynamiccharacteristics such as charge storage, voltage dependentcapacitance and reverse recovery time. Less commonlyacknowledged and manufacturer specifi ed is diode forwardturn-on time. This parameter describes the timerequired for a diode t ...

Abstract: This document details the Riverside (MAXREFDES8#) subsystem reference design, a 3.3V input, 12V (15V) output, isolated power supply. The Riverside reference design includes a 3W primary-side transformer H-bridge driver for isolated supplies, and one wide input range and adjustable output ...

高的工作电压高达100V N双N沟道MOSFET同步驱动 The D810DCDC is a synchronous step-down switching regulator controller that can directly step-down voltages from up to 100V, making it ideal for telecom and automotive applications. The D810DCDC uses a constant on-time valley current control architecture t ...

DC/DC 升压IC：The FP6291 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.25 Ω power MOSFET make this regulator highly power efficient. The internal compensation network also minimizes as much as 6 external component counts. The non-inverting input of error amplif ...

  As the performance of many handheld devices approachesthat of laptop computers, design complexity also increases.Chief among them is thermal management—how doyou meet increasing performance demands while keepinga compact and small product cool in the user’s hand?For instance, ...

  Video cable driver amplifi er output stages traditionallyrequire a supply voltage of at least 6V in order to providethe required output swing. This requirement is usuallymet with 5V supplies by adding a boost regulator or asmall local negative rail, say via the popular LT®1983-3.Such ...

  Automotive batteries, industrial power supplies, distributedsupplies and wall transformers are all sources ofwide-ranging high voltage inputs. The easiest way to stepdown these sources is with a high voltage monolithicstep-down regulator that can directly accept a wide inputrange and prod ...
