The Grid-Clamped Delay Multivibrator, a Simple Pulse Generator

摘要

The grid-clamped delay multivibrator is a simple one-tube circuit similar to the delay multivibrator, but providing better stability for generating pulses in a range from about 1 to 50 micro-sec duration. The circuit is unusually independent of variations in tube characteristics and supply voltages. The circuit is described, design formulas are derived, and several circuit variations are given. Also included is a practical schematic of the grid-clamped circuit that is used as a 5-microsec gate-pulse generator in the demodulator of a pulse -code - modulated timing system.
