This is a simple JFET pierce crystal oscillator. We can use a wide frequency range of crystal using this circuit without circuit modification. Here is the circuit : This circuit uses Q, 2N3823, that is maintained thus insuring good stability of frequency because the crystal does not loaded by the JFET.

This is a low-current temperature sensors with a single-wire output. The number of pins that needed to interface with a microprocessor is minimized by this circuit because it uses a single-wire output. This circuit can be used in many appplication such as critical µP and µC monitoring, cell phones, networking and telecom equipment, hard drives/tape drives, portable battery-powered equipment, medical […]
