New Clock-Feedthrough Compensation Scheme for Switched-Current Circuits
نویسندگان
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.

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...

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...
متن کاملA practical implementation scheme for Component Simulation SI filters - Circuits and Systems, 1995., Proceedings., Proceedings of the 38th Midwest Symposium on
This paper presents a very practical method to implement the new switched-current structures recently proposed by the authors. Those structures are obtained by a one-to-one simulation of the components of a continuous-time Transconductance-C model. The resulting circuits operate with doubled sampling rate (sampling the input and updating the output at each phase), don’t present switching glitch...
متن کاملClockfeedthrough Compensation Technique for Switched-Current Circuits
A new clockfeedthrough compensation scheme for switchedcurrent systems is proposed. The circuit cancels both the signal dependent and the constant clockfeedthrough term. It is shown that this concept can be used to derive various sample-and-hold circuits, depending on the desired clock frequency, accuracy, and power dissipation.
