Low-Power Tuneable Analog Circuit Blocks Based on Nanoscale Dual-Gate MOSFETs

We illustrate unique examples of low-power tunable analog circuits built using independently driven nano-scale DG-MOSFETs, where the top gate response is altered by application of a control voltage on the bottom gate. In particular, we provide examples for a single-ended CMOS amplifier pair, a Schmitt Trigger circuit and a OTA-C filter, circuit blocks essential for low-noise high-performance integrated circuits for analog applications. The topologies and biasing schemes explored here show how the nanoscale DG-MOSFETs may pave way for efficient, tolerant and smaller circuits with tunable characteristics.
