Title: High efficiency amplifier output level and burst control
Inventor: MCCUNE EARL W
IPC: H03F1/02
Filed: 2000-02-09
Granted: 2001-05-01
Abstract: The present invention, generally speaking, provides for high-efficiency power control of a high-efficiency (e.g., hard-limiting or switch-mode) power amplifier. In one embodiment, the invention exploits the recognition that, for a constant-resistance circuit, power is equal to the square of the voltage across the circuit divided by the resistance of the circuit. In the case of certain switch mode amplifiers, such as class E and class F amplifiers, as well as saturated linear amplifiers, the amplifier may reasonably be regarded as having a constant resistance with varying power supply. In an exemplary embodiment, the supply voltage is controlled using a combination of two stages, a switch-mode converter stage that accomplishes gross power level control and a subsequent linear regulator stage that accomplishes more precise power envelope control, e.g., burst control. Control circuitry for the amplifier is simplified by combining control signals for power amplifier ramp-up transition, power level during a TDMA burst, and ramp-down transition, into a single control signal, and by eliminating feedback control (which also climinates errors in the feedback control of output power due to the use of detecting diodes). Output noise from the variable output switch-mode voltage converter stage is filtered using the linear regulator stage that accomplishes burst control, further increasing circuit efficiency. Energy efficiency during ramp-up to the desired output power, during the burst at all output power levels, and during ramp-down from the transmitted power, is maximized. Reasonable expected efficiencies for the switch-mode converter stage and the linear regulator stage are 90% and 80%, respectively. A high-efficiency switch-mode amplifier may have an efficiency on the order of 80%, enabling an overall efficiency of greater than 50% to be achieved, comparing very favorably with current efficiencies of about 10%.

Title: Multibit sigma-delta modulators with reduced based tonal problem by using dynamic element matching technique
Inventor: GUO TAI-HAU
IPC: H03M7/00
Filed: 2001-05-28
Granted: 2002-03-11
Abstract: A technique which is referred to as ""advanced data weighted averaging"" for reducing baseband tonal problem and intermodulation distortions in multibit sigma-delta modulators employing data weighted averaging (DWA) is disclosed. An multibit analog-to-digital converter includes an analog loop filter, an (N+1)-level quantizer, a stepping element selection election logic, an internal (N+1)-level digital-to-analog converter (DAC), and a decimation filter, where N is an integer greater than one. This technique can shift the mismatch tones and intermodulation distortions outside the baseband by changing the starting element of each rotation orderly. According to the principle of this technique and the output of the (N+1)-level quantizer, the stepping element selection logic produces a set of control signals to select the N unit elements in the internal (N+1)-level DAC. This technique can also be applied to a multibit sigma-delta digital-to analog converter.
