Abstract
An apparatus for affecting operation of a signal treating device that is provided an operating voltage ranging between an upper voltage limit and a lower voltage limit for treating at least one input signal includes: a respective dynamic bias unit coupled with the signal treating device for each respective input signal of the at least one input signal; and a respective transconductance control unit coupled with each the respective dynamic bias unit. Each respective dynamic bias unit and transconductance control unit cooperates to operate the signal treating device responsive to the at least one input signal approaching at least one of the upper voltage limit and the lower voltage limit.
Claims20
An apparatus for affecting operation of a signal treating device;
- said signal treating device being provided an operating voltage ranging between an upper voltage limit and a lower voltage limit for treating at least one input signal;
- the apparatus comprising a respective dynamic bias unit coupled with said signal treating device for each respective input signal of said at least one input signal;
- and a respective transconductance control unit coupled with each said respective dynamic bias unit;
- each said respective dynamic bias unit and said transconductance control unit cooperating to operate said signal treating device responsive to said at least one input signal approaching at least one of said upper voltage limit and said lower voltage limit.
An apparatus for dynamically biasing a signal treating device;
- said signal treating device operating between an upper voltage limit and a lower voltage limit while treating at least one input signal;
- the apparatus comprising at least one dynamic bias control unit coupled with said signal treating device;
- and at least one transconductance control unit coupled with each respective dynamic bias unit of said at least one dynamic bias unit;
- said at least one dynamic bias unit and said at least one transconductance control unit cooperating to bias said signal treating device responsive to treat said at least one input signal substantially at least one of said upper voltage limit and said lower voltage limit.
A method for affecting operation of a signal treating device;
- said signal treating device being provided an operating voltage ranging between an upper voltage limit and a lower voltage limit for treating at least one input signal;
- the method comprising the steps of:
- (a) in no particular order:
- (1) providing a respective dynamic bias unit coupled with said signal treating device for each respective input signal of said at least one input signal;
- and
- (2) providing a respective transconductance control unit coupled with each said respective dynamic bias unit;
- and
- (b) operating each said respective dynamic bias unit and each said transconductance control unit cooperatively to operate said signal treating device responsive to said at least one input signal approaching at least one of said upper voltage limit and said lower voltage limit.
