The output voltage of SEPIC can be greater, less or equal to its input voltage, and respond more gracefully to short- circuit output. Working process of SEPIC working in discontinuous conduction mode (DCM) was analyzed in detail. The parameter calculation method of SEPIC is also given. The relationship between duty ratio and output voltage of SEPIC working in continuous conduction mode (CCM) and DCM...
In this paper, we present a novel wearable flexible supercapacitor with the conductive carbon-nanotube (CNT)/fabric electrode and PVA/H3PO4 solid-state electrolyte, which is cost-effective and can be easily mass produced. Two kinds of fabric as the electrode substrates, cotton knitting fabric and polyester-fiber knitting fabric, are used for comparison respectively. The flexible fabric-based supercapacitors...
An improved current bleeding CMOS mixer is designed in this paper. The conversion gain of the mixer is increased and the flicker noise of the mixer is reduced by inserting the inductor to form resonant circuit with parasitic capacitors of the source ports of the switch transistors in Gilbert mixer. The mixer is designed by using SMIC 0.18 um CMOS process. The simulated results show that the mixer...
Our primary objective in this work is the accurate measurement of complex dielectric constant and conductivity of unknown liquids. In this paper we present design, fabrication, and testing results for an IDC (interdigitated capacitor) electrode sensor for use as a fluid monitoring component that can be integrated into a microfluidic system. Unlike prior work we show how to accurately extract both...
Three types of novel DGSs are proposed firstly in this paper. The electric and magnetic coupling structures for three types of DGS are studied respectively. The S-parameters show that different coupling structures can cause different frequency responses, especially the stopband characteristics and the position of transmission poles. At the same time, the similar coupling structures have similar frequency...
A 32 times 32 register file based on complementary pass-transistor adiabatic logic (CPAL) has been fabricated with chartered 0.35 mum process. All the circuits except for the storage cells employ CPAL circuits. The storage cell is based on the conventional memory one. For comparison, a conventional 32 times 32 register file is also embedded in the chip. Full-custom layouts are drawn. The energy and...
