Patent ID: 7688141

Claim:
A transimpedance amplifier (TIA) comprising: N cascaded pairs of transconductance amplifiers, where N is an integer greater than 1, and wherein each one of said N cascaded pairs includes: a first transconductance amplifier having an input and an output; a second transconductance amplifier having an input and an output, wherein said input of said second transconductance amplifier communicates with said output of said first transconductance amplifier; and a first resistance having first and second ends that communicate with said input and said output of said second transconductance amplifier, respectively; and a second resistance having a first end that communicates with said input of said first transconductance amplifier of a first one of said N cascaded pairs, and a second end that communicates with said output of said second transconductance amplifier of a last one of said N cascaded pairs.
