Abstract
A limiter-amplifier device usable for burst mode communications. In one variation, the device includes a resistor bypassable via a switch, a capacitor, and a limiter-amplifier in series. In operation, in a first phase, the capacitor is discharged to ground via switches. In a second phase, the resistor is bypassed and the capacitor is charged while between the received signal and ground, via switching. In a third phase, in a fast tracking mode, the resistor is bypassed, and the capacitor is placed in series with the limiter-amplifier via switching, and in a slow tracking mode, the resistor is not bypassed, such that the resistor and capacitor are in series with the limiter-amplifier. In additional variations, the resistor is so placed such that less switching functions are needed to bypass the resistor, and additional resistors are optionally used in series with the switches to avoid exceeding current limitations for the switches.
