The trend in ADCs and DACs is toward higher speeds and higher resolutions atreduced power levels. Modern data converters generally operate on ±5V (dualsupply) or +5V (single supply). In fact, many new converters operate on a single +3Vsupply. This trend has created a number of design and applications problems whichwere much less important in earlier data converters, where ±15V supplies and ±10Vinput ranges were the standard.

A recent trend in the design of portable devices has beento use ceramic capacitors to filter DC/DC converter inputs.Ceramic capacitors are often chosen because of theirsmall size, low equivalent series resistance (ESR) and highRMS current capability. Also, recently, designers havebeen looking to ceramic capacitors due to shortages oftantalum capacitors.

In an increasing trend, telecommunications, networking,audio and instrumentation require low noise power supplies.In particular, there is interest in low noise, lowdropout linear regulators (LDO). These components powernoise-sensitive circuitry, circuitry that contains noisesensitiveelements or both. Additionally, to conserve power,particularly in battery driven apparatus such as cellulartelephones, the regulators must operate with low input-tooutputvoltages.1 Devices presently becoming availablemeet these requirements (see separate section, “A Familyof 20mVRMS Noise, Low Dropout Regulators”).

將現行的供暖計費方式由按建筑面積計費變為按消耗的熱能計費是供暖計費方式發展趨勢,為了滿足這一計費方式變化的需要,設計了基于IC卡的預付費式新型供暖計費系統,通過測量用戶采暖系統進出口的溫度和流量,計算用戶消耗的熱能,利用IC卡記錄用戶預付費的金額和當年熱能的單價,根據熱能消耗和當年熱能的單價計算用戶采暖費,根據實際發生的供暖費用和預付費金額控制供暖的開停,這一計費方式的變化使供暖計費更趨合理。 Abstract: It is trend that the mode of heat charging is changed from billing by building area to by thermal energy. In order to meet the needs of heat charging mode changing, a new system of heat charging based on IC card is proposed. The user?蒺s energy consumption is calculated by measuring the user inlet and outlet temperature and flow,using the IC card to record the prepaid amount and the current price of heat. The user?蒺s heating costs is calculated according to energy consumption and current price, according to actual heating costs and prepaid amount,the system controls the heating opening or stopping. It is more reasonable that calculated heating costs by user heat consumption

Design techniques for electronic systems areconstantly changing. In industries at the heart of thedigital revolution, this change is especially acute.Functional integration, dramatic increases incomplexity, new standards and protocols, costconstraints, and increased time-to-market pressureshave bolstered both the design challenges and theopportunities to develop modern electronic systems.One trend driving these changes is the increasedintegration of core logic with previously discretefunctions to achieve higher performance and morecompact board designs.
