Cmos Mixer

DC offset and high flicker noise are the main problems for the direct conversion CMOS mixer design. A novel even harmonic switching mixer implemented in a standard 0.18 μm CMOS process for applications in 2.45 GHz direct conversion receivers is proposed. The mixer circuit overcomes the problems of DC offset and high flicker noise. It achieves -8.24 dB gain, 5.2 dB DSB noise figure at 100 KHz, 17.25 dBm IIP3 and zero DC power consumption.

In the design engineering of high performance electromagnetic lenses, the direct conversion of electron optical design data into drawings for reliable hardware is oftentimes difficult, especially in terms of how to mount parts to each other, how to tolerance dimensions, and how to specify finishes. An answer to this is in the use of magnetostatic analytics, corresponding to boundary conditions for the optical design. With such models, the magnetostatic force on a test pole along the axis may be examined, and in this way one may obtain priority listings for holding dimensions, relieving stresses, etc..The development of magnetostatic models most easily proceeds from the derivation of scalar potentials of separate geometric elements. These potentials can then be conbined at will because of the superposition characteristic of conservative force fields.
