Hey i have designed a sample and hold circuit using a MOSFET with an input sinusoidal signal given to source and a clock signal of frequency greater than the frequency of sinusoidal signal (almost 4fs).This circuit is working well for a frequency of 100KHz however for higher frequencies of range 100MHz and 1GHz it is not working properly.Using this sample and hold circuit we have to build a high sampling rate Flash ADC.
any help on this work please
Thank you in advance
