High CMRR Instrumentation Amplifier (Schematic and Layout) design for biomedical applications

Instrumentation amplifiers are intended to be used whenever acquisition of a useful signal is difficult. IA’s must have extremely high input impedances because source impedances may be high and/or unbalanced. bias and offset currents are low and relatively stable so that the source impedance need not be constant. Balanced differential inputs are provided so that the signal source may be referenced to any reasonable level independent of the IA output load reference. Common mode rejection, a measure of input balance, is very high so that noise pickup and ground drops, characteristic of remote sensor applications, are minimized.Care is taken to provide high, well characterized stability of critical parameters under varying conditions, such as changing temperatures and supply voltages. Finally, all components that are critical to the performance of the IA are internal to the device. The precision of an IA is provided at the expense of flexibility. By committing to the one specific task of

300W MOSFET Broadband Amplifier

300W MOSFET Broadband Amplifier Circuit

The back scheme will provide the best Motorola for any MRF141G typical application (including the functions of stabilization parasites), a power of broadband RF MOSFET put a conservative 300 watts rated through the broadcast band FM. The flange on the MRF141G be mounted on a heat sink, a copper plate 5 / 16 "thick and 6" x 8 ", which is mounted to the heat sink with 6-32 machine screws in the case that the heat sink is drilled and exploited.

CAUTION: This amplifier operates at very high energy ranges. You could receive significant RF burns if it comes in contact with open coaxial power of the amplifier. Also, if your transmitting antenna is mounted on the ceiling, and it should fly in a wind storm despite eating all the power of this amplifier, you can start a fire in certain types of roofing insulation! Be very careful with the use, installation and operation of the unit.
