  1. This converter includes not only analog parts such as the bandgap voltage reference, voltage pump, sample / hold unit, one bit comparator of high precision, multiply - by - two and difference unit, but also digital parts such as register and multiplexer. so the design of this type of converter is mixed signal design

    模數轉換器的內部電路包括基準源、降壓模塊、抽樣保持電路單元、高精度的1bit比較器、倍乘作差單元等模擬電路模塊，以及寄存器組、選擇器等數字電路模塊，屬于數模混合電路。
  2. In the meantime, the all sub - circuits are also designed and emulated carefully including inverter, rs type flip - flop, voltage reference circuit, error amplifier, voltage comparator, sawtooth - wave generator, pwm comparator, soft activation circuit and so on. as a result, all of the sub - circuits answer the requirements. this chip has taped out with the 0. 5um mix - signal process of csmc

    本文利用cadenceeda集成電路設計工具、 spectres模擬工具，對集成電路內的各個模塊包括反相器、基本rs觸發器、基準電壓電路、誤差放大電路、電壓比較電路、鋸齒波振蕩發生電路、 pwm比較電路、軟啟動電路、驅動電路等進行了具體的設計和模擬，且達到了預先設定的指標。
  3. Advanced fpga technology is introduced to improve the integration of digital circuits, and all digital circuits in the original module are integrated in the fpga chips, which could not only reduce the cost, but also improve the reliability and measurement precision of the circuits. high speed digital signal processor ( dsp ) is selected as the coprocessor instead of scm ; it can receive all kinds of commands sent from vxi, analyze and execute the commands, harmonize each section of the module and process the data. higher - conversion - speed comparator chip is adopted to convert the input signals being measured into square waveform signals which could be identified by fpga chip ; it can expand the measurement range of frequency dramatically

    本文在原有vxi總線四通道計數器模塊的設計基礎上，通過對原模塊缺陷的分析，採用一些新的技術和新的電子器件來重新設計該計數器模塊:採用最新的fpga技術來提高數字電路的集成度，將原模塊中的所有數字電路全部集成在fpga晶元中，這樣不僅能節約成本，還能提高電路的可靠性和測量精度;採用高速的數字信號處理器（ dsp ）取代原有的單片機作為協處理器，來接收vxi發來的各種命令，分析命令、執行命令、協調模塊各部分的工作以及對數據的處理;採用轉換速率更高的比較器晶元將輸入的被測信號轉換為fpga晶元能夠識別的方波信號，能極大提高測量頻率的范圍;採用d / a轉換晶元和隔離運算放大器得到隔離通道所需的比較電平，該比較電平值能夠根據實際需求進行設置，能增強模塊的使用靈活性。
  4. Rc and other relaxation oscillators just will not do since amplitude noise in whatever circuit functions as a comparator will appear as phase noise on the output signal

    Rc諧振器以及其它一些張弛振蕩器不能滿足要求，這是因為它們的核心是電壓比較器，需要利用電壓信號的波動（噪聲）來獲得穩定的輸出，這種波動就構成了時鐘的抖動。
