Miniaturization has always been a crucial challenge in the field of antenna engineering. In the recent past a number of researchers have shown that fractal geometry have potential to design smaller, broad band and multi band antennas. In this proposed work performances of log periodic fractal antennas of different flare angles have been investigated. Simulation results show that fractal log periodic...
An improved frequency compensation technique is presented for low-power low-voltage three-stage operational amplifiers with high capacitive loads. The technique uses single RC Miller compensation and a direct gain enhanced feedforward path from the input to the output. With a load capacitance of 300 pF, the amplifier nominally achieves a dc gain of 74 dB, a 3-dB bandwidth of 2.9 kHz, a 52 degrees...
