Resistance Agc Attenuators for Transistor Amplifiers
This research is aimed at problems of interest in communication systems. Principles of transistor circuit design and practical limitations imposed by available devices are being investigated for circuits useful in a wide variety of applications. At the present time problems pertaining to gain control in transistor amplifiers are being investigated. The study of noise in semiconductors is a clos...
متن کاملDesigning and Building Transistor Linear Power Amplifiers
Putting Power in the Antenna Figure 2 is the block diagram of an experimental single-band 36 dB gain 5 W linear amplifier that may be easily constructed using whatever output device is available. Two noteworthy differences between Figure 2 and other commonly published circuits are the use of a resistive attenuator and low-pass filter between the driver and final stage, and the floating ground a...
متن کاملSimple way of teaching transistor amplifiers
For small signal analysis a simple change from commonly used tranconductance gm to transresistance rm=1/gm leads to a significant simplification of all equations. Moreover these equations are much easier to memorize since they have a form of resistor ratio for CE (CS) and CB (CG) configurations and the form or resistor divider for CC (CD) configuration. With presented approach most of students ...
متن کاملConstant-resistance Agc Attenuators for Transistor Amplifiers
Following the suggestion made in the Quarterly Progress Report of January 15, 1955, we have built a variable-gain bandpass amplifier, centered at 9. O0 Mc/sec and having a nominal bandwidth of 1. 7 Mc/sec, with tetrode transistors. The amplifier in Fig. X-l consists of four synchronously-tuned stages, two of which are gain-controlled by means of constant-resistance agc attenuators. The pertinen...
متن کاملCharge transformer to enhance noise performance of single-electron transistor amplifiers in high-capacitance applications
Following the discovery of Coulomb blockade phenomena arising from discreteness of charge and the advances in nanofabrication techniques, we have been able to make new kinds of devices that enable us to control and measure the motion of a single electron. One of the most exciting examples of such a device is a single electron transistor ~SET! which is an extremely precise solid-state electromet...
