forms one plate. Sound pressure moves one of its plates. The movement of the plate changes the capacitance. The electrets capacitor is connected to an FET amplifier. These microphones are small, have excellent sensitivity, a wide frequency response and a very low cost. First amplification stage: This is a standard self biasing common emitter amplifier. The 22nF capacitor isolates the microphone from the base voltage of the transistor and only allows alternating current (AC) signals to pass. The tank

It is to give brief picture that power amplifier (PA) is a critical component that is capable to deliver high power for UWB transmitter. However, the implementation of Radio Frequency (RF) power amplifier is one of the challenging aspects in emerging

effective electronic embedded blind stick keeping in mind the limited resources. The significant design of this smart blind stick is the use of a reflective technique that is known as “diffuse scanning method” that is cost effective and will also only help in rehabilitation of blind individuals all around the world especially in poor countries where rehabilitation is quite limited to specific individuals. Significant components used are IR emitter, IR receiver, potentiometer and amplifier to form prime

) Description of the HPGe gamma-ray spectrometer A high resolution gamma detection system was used for gamma analysis. This system consist of an ORTEC hyper pure germanium detector (HPGe), model number GEM- 15190, coaxial type detector with a serial number 27-P-1876A recommended operating bias, negative 3 Kv. The detector used has crystal diameter 49.3 mm, and crystal length 47.1 mm. The HPGe detector has a full width at half maximum (FWHM) 0.9 keV at the 122 keV gamma transition of Co-57 and 1.9

Abstract - Operational amplifiers (Op-Amps) are basic building blocks of a wide range of analog and mixed signal systems. Basically, Op-Amps are voltage amplifiers used for achieving high gain by applying differential inputs. As CMOS technology is most suitable for realizing VLSI system, it leads to continues trend in scaling down the size of transistor. Hence, reduced power dissipation is one of the challenges in front of most of designers. However, Power dissipation can be reduced by reducing either
