  • 帶有增益提高技術的高速CMOS運算放大器設計

    設計了一種用于高速ADC中的高速高增益的全差分CMOS運算放大器。主運放采用帶開關電容共模反饋的折疊式共源共柵結構,利用增益提高和三支路電流基準技術實現一個可用于12~14 bit精度,100 MS/s采樣頻率的高速流水線(Pipelined)ADC的運放。設計基于SMIC 0.25 μm CMOS工藝,在Cadence環境下對電路進行Spectre仿真。仿真結果表明,在2.5 V單電源電壓下驅動2 pF負載時,運放的直流增益可達到124 dB,單位增益帶寬720 MHz,轉換速率高達885 V/μs,達到0.1%的穩定精度的建立時間只需4 ns,共模抑制比153 dB。

  • In C Algorithms for Real-Time DSP, author Paul M. Embree presents a complete guide to digital signal

    In C Algorithms for Real-Time DSP, author Paul M. Embree presents a complete guide to digital signal processing techniques in the C programming language. This book is structured in such a way that it will be most useful to the engineer who is familiar with DSP and the C language, but who is not necessarily an expert in both. All of the example programs in this book have been tested using standard C compilers in the UNIX and MS-DOS programming environments. In addition, the examples have been compiled using the real-time programing tools of specific real-time embedded DSP microprocessors (Analog Devices ADSP-21020 and ADSP-21062 Texas Instruments TMS320C30 and TMS320C40 and AT&T DSP32C) and then tested with real-time hardware using real-world signals.
