A biasing technique using a current switch and a one to one current mir- ror as used in bipolar technologies. For the RF front-end transceiver, zero- intermediate frequency scheme is used as there is no image- rejection problem and it consumes less power. - ITH the development of wireless communication, the reconfigurable radio frequency integrated circuit (RFIC) and broadband data conversion circuit facing multi-standard and multimode wireless communication is very important. Index Terms- constant g m, Low power CMOS, 180nm technology, gain margin, phase margin 1 I NTRODUCTION The input transistors operate in weak inversion, which have big gm/Id value, so the power consumption is reduced.

Using this scheme, the Op-amp can obtain a gain bandwidth of 17.3-MHz and a DC gain of 83.67 dB according to the output load.

A constant transconductance is ensured for the whole common-mode input range and the class AB output stage provides a full voltage swing.
