<p>Method for the compensation of the offset error deriving from the injection of clockfeedthrough charge in fully differential circuits including capacitors periodically switched through at least one useful electronic switch (MC) biased at given reference voltage. The early injection of a parasitic charge in the same capacitance path of said useful switch is provided, having magnitude and sign such to be substantially compensated and cancelled by the clockfeedthrough charge, subsequently injected at the useful switch (MC) opening.</p> |
