Dear all,
I have seen most of the book said that PMOS is lower flicker noise compared with the NMOS transistor. Therefore, could I use PMOS in the LNA, mixer or VCO in order to have lower noise figure?
Actually, I know the mobility of the PMOS is slower than the NMOS. Therefore, the operating frequency maybe lower. Except this, what is the weak-points using PMOS instead?
Thanks
