Background: Sensing of biomedical signals is crucial for monitoring of various health conditions. These signals have a very low amplitude (in μ V) and a small frequency range (< 500 Hz). In the presence of various common-mode interferences, biomedical signals are difficult to detect. Instrumentation amplifiers (INAs) are usually preferred to detect these signals due to their high commonmode rejection ratio (CMRR). G Read More

Background: In this paper we have design and analyzed 4-bit binary to 4-bit gray code and 4-bit gray to 4-bit gray code converter using dual control dual semiconductor optical amplifier terahertz optical asymmetric demultiplexer (DCDS-TOAD).

In this paper, we have simulated a bi-organic polymer multilayered Light Emitting Diode (LED). It presents the transient analysis of the OLED device. Poly (9, 9-dioctylfluorene) (PFO) is used as an interlayer between Hole Transport Layer (HTL) and Lithium fluoride (LiF) which is responsible for enhancing the electron injection in the device. Hence, it is called as Electron Injection Layer (EIL). PFO acts as a photo catalyst, which im Read More
