An invention for smart signal clipping and clamping...
Any analog signal processing application requires the unwanted signal spikes to be trimmed off, while retaining the desired signal at a reference DC (Direct Current) level to allow further processing. Generally, the signal clipping operation is performed by a clipper circuit, while the desired DC level restoration is achieved using a clamper circuit. As both the circuits are very essential for waveform processing, almost all electronic circuits have them, but as separate, manually-reconfigurable entities. However, as the real-time electronic applications necessitate compact, power-efficient and lossless circuit designs, manually reconfiguring the individual clippers and clampers affects the smooth processing of signals. So, can a conjoined use of clipper and clamper be feasible and beneficial? Certainly, yes, as per the invention from Haribabu Gurju, Paramesha R, P. Janani Durga, Dr. Avani A. Vithalani, Dr. Namrata V. Langhnoja, Dr. Himanshu D. Nayak and Balvant Jivabhai Makwana. Actually, the inventors have achieved adaptive signal control with a circuit integrated with both clipper and clamper. The special unit of their invention was a diode matrix, which allowed dynamic switching between clipping and clamping operations based on predefined thresholds. The inventors have assured that their smart dual-mode clipper-clamper circuit employs minimal hardware, finding applications in protection circuits, waveform shaping and preprocessing analog signals in communication as well as measurement systems. However, there are also ways to upgrade this invention. Few functional entities, upon which the future inventors could contribute include: (i) Programmable diode matrix utilization; (ii) Novel diode materialization; (iii) Adaptive tuning of threshold for dynamic switching; (iv) Optimal placing and sizing of clippers, clampers or diode matrix and (v) Machine Learning (ML)-based signal control and waveform shaping.
