Design and Implementation of Low Delay Multi-Channel Synchronous Pulse Generator

In this study, a multi-channel output synchronous pulse generator with adjustable phase and pulse width was designed to ensure phase coherence among multiple channels in a multi-channel synchronous pulse control system. The synchronous pulse generator with multiple outputs was constructed using discrete devices. The modulation of the output pulse width and the delay between channels was achieved by adjusting the resistance-capacitance characteristics of the RC circuit and the logic characteristics of the D flip-flop. The experimental results indicated that the synchronous pulse generator can achieve continuous and low-delay error-free triggering output for hundreds of cycles. At 10 V output, the modulation range was 210 ns ± 30 ns, with a maximum delay between channels of less than 60 ps and a rise time about 1 ns. This system can be used in various high-precision multi-channel synchronous control systems.
