A 2.4-GHz low power polar transmitter for wireless body area network applications

Christian Enz, Vladimir Kopta, Franz Xaver Pengg

A 2.4 GHz low power polar transmitter is proposed in this paper. A dynamic biasing circuit, controlled by a digital envelope signal, is used as a direct digital-to-RF envelope converter. It effectively linearizes the input-output characteristic of the over ...

Submicrometer Organic Thin-Film Transistors: Technology Assessment Through Noise Margin Analysis of Inverters

Christian Enz, Jean-Michel Sallese, Rolando Ferrini, Frédéric Zanella, Nenad Marjanovic, Franz Xaver Pengg

In this paper, we propose a methodology to evaluate the potential of submicrometer organic thin-film transistors (OTFTs) with nanoimprinted gate and self-aligned source and drain contacts. In the first step, the dedicated static model we previously reporte ...
