A 3–8 GHz broadband mixer is presented in this paper. This broadband mixer is low power and high conversion gain. It provides current reuse and ac-coupled folded switching. This mixer is designed in TSMC 0.18-μm CMOS technology. This broadband mixer achieves simulated conversion gain of 9 ± 1.5 dB, a single sideband noise figure lower than 15.2 dB and IIP3 batter than −7 dBm. From 3–8GHz, at su...

In this paper, a 2.4GHz low power downconversion mixer with high linearity for direct-conversion receivers based on a standard 0.18um CMOS technology is proposed. In the circuit design, Gilbert cell architecture and Common-Gate configuration are used. A simple buffer is applied in the IF output. Simulation results show that the mixer can operate at 2.4GHz and obtain the conversion gain of 11.08...

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.

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...

In this paper, a 1.2-V RF front-end realized for the personal communications services (PCS) direct conversion receiver is presented. The RF front-end comprises a low-noise amplifier (LNA), quadrature mixers, and active RC low-pass filters with gain control. Quadrature local oscillator (LO) signals are generated on chip by a double-frequency voltage-controlled oscillator (VCO) and frequency divi...

This paper presents a 20–32-GHz wideband BiCMOS mixer with an IF bandwidth of 12 GHz. The mixer utilizes an inductive peaking technique to extend the bandwidth of the downconverted IF signal. To our knowledge, the proposed mixer achieves the widest IF bandwidth using silicon-based technologies in -band. Analytical expressions for the conversion gain and output noise of the proposed mixer are pr...

In this paper, the control over the second gate voltage in a dual-gate FET resistive mixer is employed for amplitude remodulating the response signal in a retrodirective array. A resistive mixer is integrated with an aperture coupled square patch, and a data signal voltage, Vg2s(t), is appropriately conceived in order to control the magnitude of the device time-varying output conductance. Measu...

We report on the first THz balanced mixer/upconverter using a Schottky diode MMIC chip. Using an optically pumped laser at 1562 GHz as an LO source with a coupled power of about 1 mW, and 1 mW input at an IF frequency of 10 GHz, we obtained a sideband output power of 23 uW (sum of two sidebands). As a mixer, at an LO of 1621 GHz, we obtain a conversion loss of 12.4 dB DSB and a noise temperatur...

Continuous powder mixing is an efficient alternative in high volume manufacturing of powder-based products. A new method is communicated in this paper to determine the effects of different operating conditions andmixer configurations onmixing performance. Themain idea of the proposedmethodology is the utilization of experimental residence time distribution (RTD) measurements to (a) determine th...

This paper presents a qualitative control of a fluid mixer, which is a multivariable and intrinsically non-linear plant. The mixer has as inputs two fluids of different colours and the output is the colour of the resulting mix. The control system consists of two independent fuzzy controllers which are responsible for maintaining the water level at a given height and for adjusting the colour of ...

An open structure SIS receiver, used already for astronomy at 345 GHz was tested at 470 and 690 GHz. Receiver noise temperatures considerably better than those of standard systems based on Schottky diode mixers were accomplished. A specific merrit of this system is the option to change the range of input frequencies by simply mounting a specific mixer element in a standard mixer block and by ex...
