Abstract :
This work is a CMOS Start Up Circuit designed which can supply the current flow (ISTART) adjustable to the clock oscillator for digital system generally. The circuit designed can be assigned start current value by giving the appropriate reference voltage (VBIAS). The current value is set to adjust in the range of 0 to 1.35 mA. The reference tune voltage is in the range of 0-5V to follow voltage value of microcontroller in present. In addition, while the circuit to obtain signals to PWD (power down) that current value flowing in start up circuit is almost zero. This means that the circuit does not consume any power consumption.
