A 5.3 to 6.2-GHz Fractional-N Frequency Synthesizer with Variable Gain Automatic Frequency Calibration Using Cycle Slips in 65 nm CMOS Open
The paper presents an automatic frequency calibration (AFC) technique for a charge pump-based phase-locked loop (CPPLL) with 5–6 μsec correction time. The architecture detects frequency offset in real time while keeping the loop active and…

A 3.5 to 4.7-GHz Fractional-N ADPLL With a Low-Power Time-Interleaved GRO-TDC of 6.2-ps Resolution in 65-nm CMOS Process Open
This paper proposes a low-power design method and a low-noise phase offset calibration technique for a gated ring-oscillator time-to-digital converter (GRO-TDC), which normally consumes a large percentage of most all-digital phase-locked l…

Comparative Study of Current Controllers for Shunt Active Power Compensators used in Smart Grid Applications Open
This paper presents a comparative study among different current controllers implemented in a Shunt Active Power Compensator (SAPC) to be used in smart grid applications. During the operation of a smart grid, the SAPC should deliver sinusoi…
