Abstract
The present invention discloses a mixer comprising with an input stage () for receiving and amplifying input signals (VINP, VINN) and an output stage () for outputting output signals (Voutp, Voutn). A switching stage () is coupled between the input stage () and the output stage (), the switching stage () mixing the amplified input signals with a local oscillator signal (vlop, vlon) to produce the output signals (Voutp, Voutn) at the output stage (). An RC circuit (cop, rop; con, ron) is connected to the output stage () and adapted to move the pole of the output signals.
