A power efficient delta-sigma ADC with series-bilinear switch capacitor voltage-controlled oscillator
In low-power VLSI design applications non-linearity and harmonics are
a major dominant factor which affects the performance of the ADC. To avoid this, the new architecture of voltage-controlled oscillator (VCO) was required to solve the…

Improving color rendering index of WLEDs with convex-dual-layer remote phosphor geometry using red-emitting CaGa2S4:Mn2+ phosphor
The white-light light-emitting diode (LED), a conventional illumination
solution, usually consists of one chip and one phosphor layer, which leads to the insufficient color rendering index (CRI) in this configuration. To optimize the efficiency of…
