8 GHz high conversion gain Darlington mixer

2007 50th Midwest Symposium on Circuits and Systems, 2007
This paper describes a new Darlington AC-coupled mixer operating at 8 GHz with improved figure-of-merits. This Darlington AC-coupled mixer along with a simple AC- coupling mixer used for reference are implemented in a 0.35 mum SiGe bipolar process. The supply voltage and current consumption are 3.2 V and 28 mA.

High conversion gain broadband frequency doubler design

2010 International Conference on Microwave and Millimeter Wave Technology, 2010
This paper focuses on the design of frequency doublers operating in the RF and microwave frequency ranges. To reject the fundamental and third harmonic signal over a broadband frequency range, an active balun was employed in the broadband frequency doubler which has resulted in fundamental signal and third harmonics signal rejection better than 12 dB ...

Low noise figure, high gain, high conversion efficiency L-band EDFA

Optical Amplifiers and their Applications, 1999
We report a novel L-band EDFA uses in-line tilted fiber Bragg gratings to filter the C-band ASE. This amplifier has a low external noise figure ( 27 dB) over a 33 nm bandwidth, and high power conversion efficiency of 24.3%.

High-gain DC-DC conversion for parallel photovoltaic arrays

2013 Twenty-Eighth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2013
A new approach to photovoltaic (PV) arrays is proposed based on a parallel connection scheme. In a series-connected array, differing insolation due to shading or obstructions causes disproportionate reduction in power output. Because operating voltage is governed more by temperature than by insolation, a parallel-connected array is much more robust to ...

Vibrating Membrane Electrometer with High Conversion Gain

Review of Scientific Instruments, 1964
A vibrating membrane transducer is used as the sensing element for a high sensitivity electrometer. The method of operation provides an increased conversion gain by using a special circuit in which the electrometer current controls the displacement amplitude of a membrane forced to vibrate at its resonant frequency. The experimental transducer produces

Very high conversion gain microwave frequency doubler circuit design

Proceedings of the 43rd IEEE Midwest Symposium on Circuits and Systems (Cat.No.CH37144), 2002
This paper focuses on the design and fabrication of frequency doublers operating in the RF and microwave frequency ranges. A single PHEMT transistor is employed in a new approach which has resulted in conversion gains of 10 dB or greater. This is a significant improvement over previous realizations.

Low noise and high gain CMOS down conversion mixer

2004 International Conference on Communications, Circuits and Systems (IEEE Cat. No.04EX914), 2004
The paper represents a lowest noise ever high gain CMOS direct down-conversion mixer for 1.8 GHz applications, like GSM, PCS, etc., based on 0.18 /spl mu/m CMOS technology. The designed mixer uses the current bleeding technique and an extra inductor to improve the conversion gain and noise figure (NF).

Alternating Input Power Dividing Technique for High Conversion Gain Frequency Doubler

33rd European Microwave Conference, 2003, 2003
This paper presents a new frequency doubler scheme with significant conversion gain improvement. The new design approach utilizes switching operation of FETs. All input power, in this configuration, is directed alternately to each single branch of a pair of parallelly connected FETs corresponding with the polarity of the anti-phase input signal without

A high speed, high conversion gain RF envelope detector for SRO-receivers

2019 IEEE 62nd International Midwest Symposium on Circuits and Systems (MWSCAS), 2019
A high speed and high conversion gain envelope detector (ED) is designed for RF super-regenerative-oscillator (SRO) receivers. To reduce glitches from RC filtering used for common mode signal rejection, the proposed ED is implemented using a band-pass buffer as a first stage. To avoid introducing excessive time delay and maintain good performance under
