some problems plz help!

my queries! 1.how can we get a 3/2 clock,ie a clock output with high for 1 and a half cycle of input clock and low for one clock cycle of input? 2.why do constant current source made from BJT have high gain? 3.why is offset voltage present in saturated BJT and not in MOSFET? 4.how does putting a source follower as output stage in opamp help in avoiding loss of gain when a low value load resistor is connected to amplifier? 5.in what cases do v need to double clock a signal before presenting to a synchronous state machine? 6.why do v need to put a gate resistance in mosfet circuits? 7.you have a driver that derives a long signal & connects to an input device. at the input device ther is either overshoot,undershoot or signal threshold violations,what can be done to correct this problem?
