Transformer-Less, Reduced Volume PV Inverter Topology

Inverters are devices typically used in solar power generation systems to convert electric current to a more useful type, but are prone to failure and are the main cause of malfunction in solar power systems. Using transformer-less (TL) inverters is a desirable alternative because of their higher efficiency, lower size, and lower cost. However, TL inverters...

Phase Noise Cancelling Phase Noise Loop (PLL)

Background Electronic devices that use clocks (e.g., smartphones, cars, GPS) require stability of timing reference signals. For wireless and wireline communications applications, short-term clock stability is an important factor, and long-term stability is less of a concern due to periodic synchronizations between the radio nodes. Short-term clock...

Clock Skewing for Area and Power Optimization of ASICs Using Differential Flipflops and Local Clocking

Synchronous logic remains the dominant design paradigm of digital systems such as Application Specific Integrated Circuits (ASICs). The conventional design of sequential circuit networks is based on the assumption that every register receives the clock signal at the same time. However, guaranteeing the simultaneity of clock arrival times in practice...
