“…Rather than just the device characteristics study, this paper covers the complete study by evaluating the performance of proposed device in the applied circuit. It is to note that amplifier performance is compared with the circuit of NPN Sziklai pair and PNP Sziklai pair taken from [11] and [12] respectively.…”

A new paired configuration of opposite polarity BJTs, the “complementary Sziklai pair” is introduced in the series of multi-BJT-based devices like Darlington and Sziklai pair, and its viability is tested in small-signal common emitter (CE) and common collector (CC) amplifier configurations. The Darlington and Sziklai both face the problem of poor frequency response at a higher frequency which is addressed by the proposed configuration. The proposed pair with CE amplifier holds class-A amplification property with a high voltage gain of 200.05, a high current gain of 11.62, wider bandwidth of 1.64 MHz, and a low THD of 1.29E-6%, hence supports the potential of wide applicability in analog communication. Similarly, the proposed pair with CC configuration produces approximately a unit current gain of 0.99 with wider bandwidth of 1.90 MHz and low THD of 1.76E-6%, therefore it can be used as a current buffer in a generalized current follower circuit. Conclusively, the device structure of this new BJT pair may be considered the third consecutive member of the series of Darlington pair and Sziklai pair. The layout of the proposed CE and CC amplifier occupy small areas of 158.30 μm2 (10.23×15.47 μm) and 141.16 μm2 (10.20×13.84 μm) respectively in 180 nm process technology.

“…A simple pendulum is not ideal when it comes to measurement of acceleration due to gravity as approximations are made related to mass of thread used to hang the bob and amplitude and motion of the bob. A Compound Bar Pendulum provides much more accurate results as it is applicable to body of any shape oscillating about the known axis [7][8][9][10]. The Bar Pendulum used in undergraduate physics labs consists of a uniform rectangular metal bar (100cm x 4cm x 0.6cm) with several holes drilled along its length such that the holes pass through the centre of gravity.…”

Use of Computer interface for data acquisition and analysis is constantly being pursued and incorporated into curriculum developed at Quantum University. Several experiments at Introductory level for Science and Engineering students have already been successfully modernized, tested and implemented in the curriculum. Devices such as the ExpEyes, that offer flexibility in designing experiments, have been well received by the students and help them be better prepared for the real world technologies after graduation. In this paper, we describe alternate experimental setups for measurement of acceleration due to gravity of a Compound Bar Pendulum using ExpEyes that allows us to measure and analyze the data on a computer. The experimental analysis clearly shows that using the Ultrasonic sensor gives reliable and excellent results and proves to be an effective technique for achieving student learning outcome.
