Abstract:
A high dynamic range power supply, comprising:an oscillator assembly operating from a first power supply and produce first and second out-of-phase signals which have a gradually increasing portion;first and second transistors, coupled to receive said first and second signals respectively, and turned on by said signals to produce an oscillating output, wherein said first transistor produces a first part of the oscillating output and said second transistor produces a second part of the oscillating output;a feedback loop, including a detector sensing a level of the oscillating output and producing a signal indicative thereof, a second element comparing said signal to a reference and producing an error output indicative of the difference, said error output causing a change in said first and second drive signals;wherein said first transistor is referenced to a second power supply, having a different level than said first power supply.
