This purpose of this study is to investigate the association among mutual funds (MFs) risk measures and return parameters, evaluate mutual fund performance and also explore the best appropriate mutual fund performance measure for investment in Pakistan. Therefore, thirty-five mutual funds have been selected for the period 2007-2015. The Sharpe, Treynor, Jensen Alpha, Information ratio and Fama's Net Selectivity measures has been used to analyze MF performance. Our study findings show significant positive relation exist between Sharpe and Jenson alpha & information ratio (IR); Treynor ratio is negatively correlated to Jenson alpha and Jenson alpha is positively allied with IR. Moreover, association among performance measures, Fama's net selectivity is a major driver in leading to other measures but Sharpe and IR lead to Treynor ratio as well. Furthermore, performance measures are ranked in accordance standard deviation with the arrangement of Fama's net selectivity at top, Jenson Alpha at second, Sharpe ratio at third, IR at fourth and Treynor ratio at fifth position according to risk parameters in Pakistan. Overall, Jensen Alpha measure appears to be the best suitable mutual fund performance measure in Pakistan due to its practical nature. Finally, the Pakistani stock market index KSE100 (as benchmark) performs better than MF industry of Pakistan.

<P>In this paper, an output-capacitorless, low-dropout (LDO) voltage regulator with excellent load regulation and fast recovery time was designed using two amplifiers, which provided high gain, high bandwidth (HBW), and high slew rate (HSR). In addition, a one-shot current boosting (OSCB) circuit was added for current control to charge and discharge the parasitic capacitance at the power transistor gate during the load-current transition to improve the response time. The experimental results show that the proposed LDO regulator consumes a quiescent current of only 4.5 and can deliver a maximum load current of 200 mA, while regulating the output voltage at with a 1.2 V power supply. We experimentally verified that for a current transition from 0.1 to 200 mA, the undershoot and overshoot voltages were 260 and , with recovery times of only 0.8 and 0.85 , respectively.</P>
