AUTONOMOUS POWER AND TIMING SYSTEM
In accordance with aspects of the present invention, and power and timing supply is presented. The supply includes a power supply providing a supply voltage as a function of a load current; and a timing generator providing a frequency signal as a function of the supply voltage, wherein the supply voltage and the frequency signal are within a safe operating range.
1 . A power and timing supply, comprising:
a power supply providing a supply voltage as a first function of a load current;
a timing generator providing a frequency signal as a second function of the supply voltage,
wherein the supply voltage and the frequency signal are within a safe operating range.
2 . The supply of claim 1 , wherein the first function includes hysteresis.
3 . The supply of claim 1 , wherein the power supply uses a look-up table to determine the supply voltage.
4 . The supply of claim 1 , wherein the second function determines a range of frequencies in the safe operating range.
5 . The supply of claim 4 , wherein the safe operating range includes a zero frequency.
6 . The supply of claim 4 , wherein the frequencies in the safe operating range are above a minimum frequency.
7 . A method of providing power to a load, comprising:
determining a supply voltage from a load current to the load;
determining a frequency from the supply voltage; and
providing the supply voltage and the frequency to the load.
8 . The method of claim 7 , wherein determining the supply voltage includes calculating the supply voltage as a first function of the load current.
9 . The method of claim 8 , wherein the first function is performed with a look-up table.
10 . The method of claim 8 , wherein the first function includes hysteresis.
11 . The method of claim 7 , wherein determining the frequency includes calculating the frequency as a second function of the supply voltage.
12 . The method of claim 11 , wherein the second function is performed with a look-up table.
