چکیده
An improved clock-feedthrough compensation scheme for switched current system is proposed. Both the signal dependent and the constant clock-feedthrough terms are canceled by using both nMOS and pMOS current samplers and by adopting a source replication technique. The proposed current memory cell was fabricated with 0.6m CMOS process. Both experimental and theoretical results on clockfeedthrough error reveal substantial reduction over the existing compensation schemes.

approved: Gabor C. Temes This thesis describes compensation techniques for cascaded delta-sigma A/D converters (ADCs) and high-performance switched-capacitor (SC) circuits. Various correlated-double-sampling (CDS) techniques are presented to reduce the effects of the nonidealities, such as clock feedthrough, charge injection, opamp input-referred noise and offset, and finite opamp gain, in SC c...

Another simulation was made, with the circuit simulated in the basic form, without enhancement circuits, assuming G,,,/Gds and CgslCgd ratios of 1000, with the biasing and signal current sources assumed as ideal. This is not realistic for the basic structures, but is reasonable when it is assumed that the additional enhancement circuits are present. The result is curve “d”. The same simulation ...
متن کاملImproved Two-Step Clock-Feedthrough Compensation Technique for Switched-Current Circuits
A new clock-feedthrough compensation scheme for switchedcurrent circuits is proposed. The scheme is especially suited for the design of delay lines for high-frequency operation. The circuit operates by using an improved two-step technique, in which the input is sampled in a parallel combination of a coarse and a fine memory transistor. Since both transistors are of the same type, large switchin...

The mixed-signal circuits with both analog and digital blocks on a single chip have wide applications in communication and RF circuits. Integrating these two blocks can cause serious problems especially in applications requiring fast digital circuits and high performance analog blocks. Fast switching in digital blocks generates a noise which can be introduced to analog circuits by the common su...
