Abstract :
A low power double-balanced quadrature mixer for 403MHz medical implantable applications for direct conversion receivers is presented in this paper. The proposed mixer is designed using the current reuse bleeding technique to improve the conversion gain, noise figure (NF), and linearity. The design down-conversion mixer has a conversion gain of 9dB, a P1dB of −11dBm while the IIP3 is at −5.1dBm. The mixer dissipates 3.6mW from a 1.2V supply. LO power requirement is −5dBm. Single side band noise figure is 2.02dB at 1MHz. Low-power dissipation makes this mixer attractive for low-power highly integrated receiver applications.
