Memristor appeals to a wide research field as the fourth passive element, and its model has been a necessary topic for future circuit applications. In this letter, a novel compact model of memristor, based on the equivalent resistor topology of variable conductive filaments, is presented. Since the formation and annihilation of conductive filaments is a natural mechanism of mainstream memristor, the...
This paper proposes a novel 150-GHz single-pole-double-throw (SPDT) switch based on a rat-race coupler topology. It is designed with a 0.13-μm SiGe BiCMOS and occupies a chip area of 507 μm×542 μm. The switch achieves insertion loss of 4.0 dB/3.3 dB, isolation of 36.3 dB/35.9 dB, input return loss of 18.7 dB/12.3 dB, output return loss of 21.7 dB/26.1 dB and power-handling capabilities of 22.2 dBm/15...
It is well observed that the nonzero transform coefficients for block-based hybrid video coding is more clustered in the low frequency region while more scattered in the high frequency region. Based on this observation, hybrid variable length coding (HVLC) was recently proposed, which divides each transform block into low frequency (LF) region and high frequency (HF) region by a pre-defined breakpoint...
A step-up ZVS full-bridge (FB) converter with a primary-side energy recovery circuit (PERC) is proposed. The PERC means can recover the power loss due to high spike current hiding in primary inductance when the phase-shift switching activates. High ringing currents occurring at the beginning of the two resonances each half-period can then be smoothly transferred to DC bus and restrain the resonant...
