Title -NEW DIRECTIONS IN HIGH-SPEED ELECTRONICS: ELECTRICAL SOLITON MODELOCKING & NANOWIRE FLEXIBLE CIRCUITS
Abstract -In this talk I will present the results of two research projects that offer new directions in high-speed electronics. The first combines the physics of the electrical soliton with a novel circuit design to create the first electrical soliton modelocked oscillator. This new oscillator self-generates a periodic train of sharp, electrical pulses and creates a new paradigm for pulse generation in applications such as high-resolution sampling, TDR, and UWB radar and ranging systems. The second project uses semiconductor nanowires to build low cost, high-speed macroelectronic circuits on glass and plastic substrates. Our latest results in the VHF frequency range demonstrate the viability of developing true RF nanowire circuits on transparent and flexible substrates, enabling the integration of high-performance RF electronics with everyday objects.
