Wide-Range Frequency Divider Using Hybrid Circuits

The limitation on the range that a monostable multivibrator can be used as a frequency divider is studied and identified as due to the recovery time of the circuit. It is shown that by coupling a chain of bistable flip-flops to the mono the frequency division ratio can be increased substantially while maintaining the basic flexibility of the mono as a frequency divider. The ultimate ceiling on the variability of the hybrid divider is attributed to the small timing jitter of the mono.
