Basically design of OTA is totally based on MOS transistors that are essentially non linear which leads to deterioration The proposed circuit of two-stage OTA is used for low power consumption, increasing transconductance and efficiency of the circuit. Due to the operation of all the transistors in saturation region the output voltage is increased. By using proposed circuit the performance of two stages OTA is enhanced. Performance parameters for the designed circuit are as power consumption 38.13μW, gain margin 57.9dB, phase margin 104.31o, slew rate 30.76Vμ/sec etc. By introducing FinFET techniques the required power supply for the circuit decreases to 0.7V.

They can also be designed as impedance matching sources for antennas or stubs filters. The ease of fabrication of devices that use transmission lines for interconnection among the other sub-components of the circuit gives it an edge over the other tedious wiring methods. Planar transmission lines specifically stand out in this regard with respect to the latest fabrication technology being used for the nanoscale development of integrated circuits and at the same time playing a major role in radio frequency communication systems.

Dual input in the circuit is compared and single output respective to the input provided is acquired from the opposite end. Comparator circuit should consume less power and should have a high speed of operation. With the proposed design the amenities of the comparator circuit is obtained. Since scaling of transistor size is taking place, so the circuit is designed in 45nm technology. The supply voltage for the circuit is also very low as compared to other conventional based design. With the proposed design the efficiency of the circuit obtained is higher than the conventional design with reduction in the leakage current and leakage power in the design. The circuit is simulated at 45 nm technology with the supply voltage of 0.7 volts.

Optical designer can do excellent aberration correction using an aspheric lens, which provides superior resolution, even with compact optics composed of a small number of elements. We report fabrication of an aspheric lens in Fused Silica using sub aperture polishing technique because traditional full aperture polishing technique is not suitable for aspheric lenses.

The single pulse energy of the amplified mode locked pulses was ~590 nJ. The effect of pre-amplifier signal strength on temporal and spectral profiles of amplified pulses were investigated experimentally. It was found that though stronger signal strength at the input of the power amplifier is useful to increase the threshold for onset of amplified spontaneous emission (ASE), however, it may lead to severe distortion in temporal profile after compression due to enhanced nonlinearity. We conclude that there is an optimum signal strength for generation of clean and smooth ultrashort pulses with low ASE contribution with in the operating range of the power amplifier. The compressed pulse duration of the amplified pulses was measured to be 280 fs.
