Circuit design covers systems ranging from complex electronic systems to the individual transistors within an integrated circuit. Moore's law has driven the worldwide semiconductor industry; as such, the expectation of continued device scaling drove fundamental research on physics, materials, devices, interconnect, leading to an enormous and diverse range of commercial electronics. As we move into the era of nanoscale devices, however, scaling-as-usual is under significant duress. The devices are smaller, but many aspects of their performance deteriorate: for example, leakage increases, gain decreases, and sensitivity to unavoidable small fluctuations in the manufacturing process rises dramatically. The Circuit and Signal Processing (CASP) Group in the Department of Electrical Engineering, Bahria University, Islamabad Campus focusses on scientific theory, analysis, design and implementation of circuits, and the application of circuit to systems and signal processing. The key research directions in circuit domain include but not limited to hardware implementation of baseband wireless communication, cryptographic algorithms, FPGA-based cyber security solutions, EMI issues in high-speed serial links and visible light communication system. The work of CASP research group in signal processing domain includes information processing as well as the theory and application of filtering, coding, transmitting, estimating, detecting, analyzing, recognizing, synthesizing, recording, and reproducing signals to solve real world problems. One of the salient features of this group is its capacity to undertake and deliver product oriented projects. In this regard, projects have been delivered to Military and Industrial Partners such as Pakistan Air Force, NESCOM, Maritime Technologies Complex.
