Us Patents

Programmable Gain Amplifier With Glitch Minimization
view source
US Patent:

6958648, Oct 25, 2005
Filed:

Aug 30, 2004
Appl. No.:

10/928371
Inventors:

Felix Cheung - Irvine CA, US
Kevin T. Chan - Pasadena CA, US
Siavash Fallahi - Newport Coast CA, US
Assignee:

Broadcom Corporation - Irvine CA
International Classification:

H03F001/36
US Classification:

330 86, 330144, 330282, 330284
Abstract:

A programable gain amplifier (PGA) has an amplifier and a variable resistor that is connected to the output of the amplifier. The variable resistor includes a resistor that is connected to a reference voltage and multiple parallel taps that tap off the resistor. A two-stage switch network having fine stage switches and coarse stage switches connects the resistor taps to an output node of the PGA. The taps and corresponding fine stage switches are arranged into two or more groups, where each group has n-number of fine stage switches and corresponding taps. One terminal of each fine stage switch is connected to the corresponding resistor tap, and the other terminal is connected to an output terminal for the corresponding group. The coarse stage switches select from among the groups of fine stage switches, and connect to the output of the PGA. During operation, one selected tap is connected to the output of the PGA by closing the appropriate fine stage switch and coarse stage switch, where the selected tap defines a selected group of the fine stage switches.

US Patent:

20030155970, Aug 21, 2003
Filed:

Feb 26, 2003
Appl. No.:

10/372778
Inventors:

Felix Cheung - Irvine CA, US
Kevin Chan - Pasadena CA, US
Siavash Fallahi - Newport Coast CA, US
International Classification:

H03F001/36
US Classification:

330/086000
Abstract:

A programable gain amplifier (PGA) has an amplifier and a variable resistor that is connected to the output of the amplifier. The variable resistor includes a resistor that is connected to a reference voltage and multiple parallel taps that tap off the resistor. A two-stage switch network having fine stage switches and coarse stage switches connects the resistor taps to an output node of the PGA. The taps and corresponding fine stage switches are arranged into two or more groups, where each group has n-number of fine stage switches and corresponding taps. One terminal of each fine stage switch is connected to the corresponding resistor tap, and the other terminal is connected to an output terminal for the corresponding group. The coarse stage switches select from among the groups of fine stage switches, and connect to the output of the PGA. During operation, one selected tap is connected to the output of the PGA by closing the appropriate fine stage switch and coarse stage switch, where the selected tap defines a selected group of the fine stage switches. Additionally, one fine stage switch is closed in each of the non-selected groups of fine stage switches. In one embodiment, the location of the closed switches in the non-selected groups is the mirror image of the location in an adjacent group. This reduces the transient voltages that occur when tap selection changes from one group to another.
