This paper analyses two front-end receiver architectures intended for GSM900 use; (i) A direct-conversion receiver, and (ii) a low-IF receiver using a poly-phase filter. The aim is to determine the circuit performance required for GSM operation and to compare this to current state-of-the-art CMOS performance. The analysis shows that direct-conversion receivers fail to meet specifications when b...

Low-power flexible logic circuits are key components required by the next generation of flexible electronic devices. For stable device operation, such components require a high degree of mechanical flexibility and reliability.

The synthesis of digital circuits is generally performed in two level logic switching algebra. But if we increase the representation domain from two level logic (N=2) to N>2 then the design of Multiple Valued Logic (MVL) digital circuits is possible. Interconnections play an important role in deep submicron designs as they affects power and area. Due to the requirement of interconnections the d...

Spintronic oscillators are nanodevices that are serious candidates for CMOS integration due to their compactness and easy frequency tunability. For a crystal oscillator to work, there must exist a feedback path with properly What practical circuits do is design such that we have a phase-shift of 180. A double balanced down conversion oscillator mixer using 90 nm CMOS technology is proposed in a...

In CMOS chips, the wider layout rules were traditionally applied to overcome latch-up issues. However, chip area with was often enlarged, and in turn cost also increased. To effectively improve immunity without enlarging area, circuit methods therefore invented. An overview on methodology used prevent issues integrated circuits (ICs) is presented this article. The solutions, including reducing ...
