Patent number: 6531975Abstract: An apparatus and method for converting digital input signals sampled at different rates to analog signals includes a digital to analog converter for each digital input signal. Each digital to analog converter receives a digital input signal and a clock signal corresponding to the sampling rate of the received digital input signal. The apparatus can also receive a set of sample rate signals indicating the sampling rate for each digital input signal. The sample rate signals are used to route each digital input signal, along with a corresponding clock signal, to a corresponding digital to analog converter (DAC). A clock error signal controls routing of the digital input signals to the DACs as well as operation of the DACs. A clock divider and ratio detector module generates the clock error signal based on intermediate clock error signals that correspond to the sample rates.Type: GrantFiled: May 24, 2001Date of Patent: March 11, 2003Assignee: Cirrus Logic, IncorporatedInventors: Brian D.

Patent number: 5406146Abstract: A circuit and method provides a low distortion buffer by using a resistive divider stage (18, 20) and a gain stage (12) whose gain is equal to the inverse of the attenuation ratio of the resistive divider to provide unity gain. Multiple inputs (14, 42, 44, . . . 46) to the buffer circuit are accommodated by an input switching network (30, 38). The gain error introduced by the resistance of the switching network (30, 38) is canceled by placing an equivalent network (60) in a feedback path of the gain stage. The preferred circuit topology is well-suited to low-voltage applications and provides a low-distortion output. Circuits for reducing power consumption (68, 70) and minimizing undesirable transients (72) are also provided.Type: GrantFiled: November 9, 1993Date of Patent: April 11, 1995Assignee: Motorola, Inc.Inventors: Lawrence F.
