Low voltage DC power supply with spike-blocking features

RFID tags, sensors embedded with buried devices and biomedical implants all operate at low voltage levels due to power limitations. The ever increasing use these embedded devices has also created a demand in the industry for lowvoltage power supplies. Since many of these circuits are mobile in...
