Abstract
  • Voltage converters or charge pumps find their use in many circuits. They are extensively used in hand held devices as cell phones, pagers, PDA's and laptops. Some of the important issues relating to design of voltage regulators for handheld devices are size, efficiency and noise. Another important factor to be considered is the discharge characteristic of the various batteries used by the handheld devices. This thesis addresses the issues of tones present in the conventional switched capacitor voltage regulator. An alternate architecture with a delta-sigma control loop to eliminate this problem is proposed. Also discussed is a method to compute the efficiency of switched capacitor charge pumps. A test chip implementing the new architecture was fabricated in a 0.72-micron CMOS process. The results of the test chip verify the improved architecture.
