A Simple Linear Time-Variant Theory of Superregeneration

We present a simple and intuitive analysis of super-regeneration that takes into account the periodically time-varying nature of a superregen operated in linear mode. We analyze the low-pass equivalent of a superregen as a starting point. Insights from this analysis guide the formal derivation of the amplifier's time-dependent impulse response, as well as of the operating conditions under which it is valid. Using the impulse response, we can easily determine the amplifier's response to arbitrary inputs as well as its frequency domain properties.
