In this work, a field effect transistor based on a deoxyguanosine derivative (a DNA base) is demonstrated. Our experiments on transport through the source and drain electrodes interconnected by self-assembled guanine ribbons (Gottarelli et al.

In this paper, a 4th-order low-pass continuous-time analog filter is presented, that is implemented with the cascade of two efficient and compact biquadratic cells, realized using the Super-Source-Follower topology. The biquadratic cell uses only two capacitors and four transistors: two transistors for the signal processing and two transistors as current sources for biasing purpose. The 4th-order filter prototype has been integrated in 0.18 µm CMOS technology. For a 33 MHz cut-off frequency, the filter performs 18 dBm-IIP3 for two tones at 2 MHz and 3 MHz, with total current of 770 µA from a single 1.8 V supply voltage.Index Terms-Analog filters, biquadratic cell, CMOS 0.18 m, continuous-time filters, low power, super source follower.
