Embodiment Construction

[0011] Specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Similar elements in several figures are labeled with similar reference numerals for consistency.

[0012] In the following detailed description of embodiments of the present invention, numerous specific details are set forth in order to provide a deeper understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known features have not been described in detail to avoid unnecessarily complicating the description.

[0013] Throughout this application, ordinal numbers (eg, first, second, third, etc.) are used as adjectives for elements (ie, any nouns in this application). The use of ordinal numbers does not imply or create any particular order of elements, nor does it limit any element to be a single element unless ...

Abstract

A processing system for equalizing a data transfer. The processing system may include a trans-conductance generator that may obtain a first clock signal. The trans-conductance generator may generate a first bias signal using a first switched capacitor and the first clock signal. The first switched capacitor may charge according to the first clock signal. The processing system may further include a biasing circuit. The biasing circuit may obtain a second clock signal. The biasing circuit may generate a second bias signal using a second switched capacitor and the second clock signal. The second switched capacitor may charge according to the second clock signal. The processing system may further include a peaking amplifier. The peaking amplifier may generate an output signal using an input signal, the first bias signal, and the second bias signal.

Description

Background technique [0001] In high frequency data transfer systems, digital signals may be transmitted over lossy channels. Thus, as the rate of data transfer increases, digital signals may experience increasing signal attenuation. In order to reduce this signal attenuation, different integrated circuits can be deployed on the transmitter side or receiver side of the lossy channel in high frequency data transfer systems to amplify the signal and remove the signal generated by the propagation of the digital signal on the lossy channel. any. Contents of the invention [0002] In general, in one aspect, embodiments relate to an equalizer circuit. The equalizer circuit includes a transconductance generator including a transistor coupled to a first switched capacitor. The first switched capacitor is configured to charge according to the first clock signal. The transconductance generator is configured to generate a first bias signal using the first switched capacitor and the ...
