CRAVE - Centre for Research in Analogue & VLSI Microsystem DEsign

Crave is involved in the design and implementation of Analogue, Digital, RF and Mixed-signal VLSI circuits & systems. Applications in wireless and wire-line communication as well as signal processing are being developed. Nano-scale semiconductor technologies ranging from 130nm to 28nm CMOS process technologies are being investegated for various VLSI System-On-Chip Implementations. MEMS sensors and actuators, Micro-fluidic micro-chip devices such as micro-actuators, micro-pumps & micro-channels for LAB-on-a-chip applications in diverse fields such as Biotechnology, DNA analysis and Food Technology are also being explored. Photonic Integrated Circuits, VLSI implementation of neural networks, fuzzy logic and specialized arithmetic processors & algorithms are also part of the centre’s activities. In addition, pioneering work on modeling biological systems (gene-protein-RNA circuits) using integrated circuits is also being carried out.
