| 6294954 | Adaptive dead time control for switching circuits Apparatus for adaptively reducing dead time in a switching circuit includes overlap detection circuitry for measuring the dead time/overlap of the switches, and control circuitry for setting the dead time to the optimum level (generally the minimum possib... | 09/25/2001 |
| 6150969 | Correction of nonlinear output distortion in a Delta Sigma DAC A delta sigma modulator of at least second order includes correction means applied to each feedback loop in the modulator, to account for systemic nonlinear output distortions. Since the output distortion is nonlinear, the correction applied to each feedb... | 11/21/2000 |
| 6097824 | Continuous frequency dynamic range audio compressor An improved multiband audio compressor is well behaved for both wide band and narrow band signals, and shows no undesirable artifacts at filter crossover frequencies. The compressor includes a heavily overlapped filter bank, which is the heart of the pres... | 08/01/2000 |
