Squaring circuits are an important building block for impulse-radio UWB non-coherent receivers. This work proposes a squarer, based on the quadratic law of saturated transistors. Such a circuit has already been proposed for lower frequency applications, therefore this work focuses on the extension to ultra wide bandwidth, with particular care to the consequences related to the deviation from the ideal quadratic law of 0.18μm CMOS transistors.

摘 要 基于AC/DC 開關(guān)電源PWM 控制芯片的工作原理，分析了其產(chǎn)生功耗的主要來源，提出了兩種減小芯 片功耗的方法，一是采用電流源和電流沉串聯(lián)方式構(gòu)成的輸出驅(qū)動電路，通過消除CMOS 電路的瞬態(tài)短路導(dǎo)通現(xiàn) 象，降低該電路模塊的功耗；二是采用跳周工作模式，使芯片在輕載和空載情況下，降低功率開關(guān)管的開關(guān)損耗。

This paper presents a low-power asynchronous implementation of the 80C51 microcontroller. It was realized in a 0.5 µ m CMOS process and it shows a power advantage of a factor 4 compared to a recent synchronous implementation in the same technology. The chip is fully bit compatible with the synchronous implementation, and timing compatible for external memory access. The circuit is a compiled VLSI-program, using Tangram as VLSI-programming language and the Tangram tool set to compile the design automatically to a standard-cell netlist. This design approach proves to be powerful enough to describe the microcontroller and derive an efficient implementation. Further, it offers the designer the possibility to explore various alternatives in the design space.
