Abstract: A pulse amplifier implemented in standard CMOS, comprises a control circuit for controlling a driver stage for driving a class D output stage that comprises a first PMOS-transistor and a first NMOS-transistor with interconnected drain contacts. A driver stage comprises a first driver and a second driver coupled with the output stage. Furthermore, a second NMOS transistor and second to fifth PMOS transistors are provided and interconnected in a way that most of the control signals needed to switch the high voltage output, specifically the drivers, are generated within a low voltage block. These factors contribute to lowering the total power dissipation.

The system and method to autonomously and selectively jams frequency-hopping signals in near real-time. The present system is able to react within a millisecond or less. The system and method incorporates a fundamental change in the detection and reaction technology, this system and method having a reaction time that is short enough to capture and then jam even the fastest frequency hopping radios in use today, without relying on prior art methods of using standard CPU driven technology. The system has the ability to automatically detect short duration signals (such as those output from frequency hoppers), to automatically determine if detected signal(s) should be jammed, and subsequently to automatically and extremely quickly activate the jamming transmitter on the frequency-hopper transmitter's frequency.
