| description | 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 nature and so are bound to operate in many different
environments, the power supply must also be capable of
ensuring a stable voltage output even under adverse
conditions. This paper analyzes and simulates a power supply
circuit that promises a low ripple factor with an element of
spike-blocking capability. It centers on a phase-modulation
technique that effectively cancels out 99.6% of ripples when
operating with a 100 mV ac input at a frequency of 10 kHz.
This active noise-cancellation technique allows for a more
stable voltage output. It also has a limited inbuilt capability to
block spikes. A 100 mV injected spike is brought down to only
6 mV without the use of other damping circuits. This work is
therefore capable of damping a large part of the variations in
the input voltage, even at low voltages. |
