Integrated circuits are the core building components of virtually all communication systems. Wireless communication systems are becoming increasingly common. They require specialized transmission components to reduce electromagnetic interference. This paper presents the design of a trapezoidal waveform generator intended for generation of waveforms with limited level and spectrum of radiated interference This limitation is important because the discussed circuit is a high-voltage function block that can drive the output antenna with relatively high-power pulses. The introduced design is based on a mix of low- and high-voltage devices; however, most of them operate in low-voltage steady and near steady conditions. The implemented design flow includes safe operating area controls, which result in the implementation of a set of overvoltage devices. The designed generator provides means of frequency and slew rate control and can produce high-quality output waveforms. The results show that this type of design can be further optimized for generating waveforms with a limited range of slew rate values. Moreover, this paper presents some operational aspects and phenomena that must be addressed to provide a design that can be practically implemented in modern high-voltage integrated circuits.

Improving microelectronic technologies has created various micro-power electronic devices with different practical applications, including wearable electronic modules and systems. Furthermore, the power sources for wearable electronic devices most often work with electrical energy obtained from the environment without using standard batteries. This paper presents the structure and electrical parameters of a circuit configuration realized as a prototype of a low-power AC-DC conversion circuit intended for use as a power supply device for signal processing systems that test various biomedical parameters of the human body. The proposed prototype has to work as a wearable self-powered system that transfers electrical energy obtained through mechanical vibrations in the piezoelectric generator. The obtained electrical energy is used to charge a single low-voltage supercapacitor, which is used as an energy storage element. The proposed circuit configuration is realized with discrete components consisting of a low-voltage bridge rectifier, a low-pass filter, a DC-DC step-down (buck) synchronous converter, a power-controlling system with an error amplifier, and a window detector that produces a “power-good” signal. The power-controlling system allows tuning the output voltage level to around 1.8 V, and the power dissipation for it is less than 0.03 mW. The coefficient of energy efficiency achieved up to 78% for output power levels up to 3.6 mW. Experimental testing was conducted to verify the proposed AC-DC conversion circuit’s effectiveness, as the results confirmed the preliminary theoretical analyses and the derived analytical expressions for the primary electrical parameters.
