A new CMOS active mixer topology can operate at 1 V supply voltage by use of SCM (switched currentmirror). Such current-mode mixer requires less voltage headroom with good linearization. Mixing is achieved with four improved current mirrors, which are alternatively activated. For ideal switching, the operation is equivalent to a conventional active mixer. This paper analyzes the performance of ...

In this paper, low voltage high gain up-conversion mixer, designed in 90nm CMOS technology, is proposed to work in the frequency band of 2.4 GHz. Current bleeding technique and current mirror topology are used in the upconversion mixer. Conversion Of an input of 100 MHz Given as intermediate frequency signal to an output of 2.4 GHz radio frequency signal is done by the proposed mixer with a loc...

The vast bulk of visible mass emerges from nonperturbative dynamics within quantum chromodynamics—the strong interaction sector the Standard Model. past decade has revealed three pillars that support this emergent hadron (EHM); namely, a nonzero gluon mass-scale, process-independent effective charge, and dressed-quarks with constituent-like masses. Theory is now working to expose their manifold...

Abstract Using the CO molecule as target, we investigate high-order harmonic generation by a bichromatic elliptically polarized laser field. This field consists of two components with commensurable frequencies and mutually orthogonal semi-major axes. Both odd even harmonics are emitted their ellipticity can be large depending on values laser-field parameters. It is often case that subsequent su...

The scaling of the CMOS technologies has a great impact on analog design. The most severe consequence is a reduction of the voltage supply. In this article, a new low-voltage folded-switching mixer with current-reuse, which operates at 1 V supply voltage, is discussed. The main advantages of the introduced mixer topology are: a high voltage gain, a low noise figure, an operation at low supply v...
