Differencing circuit cancels error caused by switching transistors capacitance. In integrate and hold circuit using JFET switch, gate-to-source capacitance causes error in output voltage. Differential connection cancels out error. Applications in systems where very low voltages sampled or many integrate-and -hold cycles before circuit is reset.
