U-129 UC3907 Load Share IC Simplifies Parallel Power Supply Design

Texas Instruments

The UC3907 family of Load Share Controller ICs provides all the necessary features to allow multiple independent power modules to be paralleled so each module supplies only its proportionate share to total load current. Many power supply manufacturers have found it economically feasible to make standard modular power supplies which are easily paralleled for higher current applications. If speci

AN-1375 Linear-In-dB RF Power Detector In W-CDMA User Equipment (Rev. A)

Texas Instruments

Since most of the deployed W-CDMA networks use FDD mode only and the W-CDMA FDD has fastclosed-loop power control in both uplink and downlink hardware implementation for RF power detection indownlink from user equipment to base station is needed in order to meet the required air interfacestandard. This application report suggests application subsystem circuits for use in closed-loop power

Converting Code from the TMS320C5x DSP to the TMS320C2xx DSP

Texas Instruments

With the introduction of the TMS320C2xx (C2xx) family of low-cost digital signal processors (DSPs) many customers are discovering that they can utilize this DSP family for designs that previously required the processing power of a TMS320C5x (C5x) DSP. Although some code has been written for the C2xx reuse of the large repository of C5x application code can dramatically speed up designs using the

TMS320C6416 Coprocessors and Bit Error Rates

Texas Instruments

The turbo and viterbi coprocessors (TCP/VCP) are programmable peripherals used to decode IS2000/3GPP turbo/viterbi codes. They are integrated into Texas Instruments TMS320C6416 digital signal processor (DSP). Turbo and viterbi decoders lie at the heart of all of the third-generation (3G) wireless standards. Their usage in 3G systems meets the tough bit-error-rate requirements and low signal-to-no

This document explains the basic connectivity of LVCMOS inputs to the CDCM6100x and recommends several methods for using the device that ensure proper operation.

AN-1803 Design Considerations for a Transimpedance Amplifier (Rev. A)

Texas Instruments

It is challenging to design a good current-to-voltage (transimpedance) converter using a voltage-feedbackamplifier (VFA). By definition a photodiode produces either a current or voltage output from exposure tolight. The transimpedance amplifier (TIA) is utilized to convert this low-level current to a usable voltagesignal and the TIA often needs to be compensated for proper operation. This a
