Switched-capacitor (SC) circuits suffer from clock-feedthrough effects as do switched-current (SI) circuits. Current-feedthrough in SI circuits is caused by non-ideal characteristics of the Metal Oxide Semiconductor (MOS) switches during the time interval when they are turned off.

A number of CFT compensation techniques are illustrated in section Most of the performance of an SI circuit is set by the limitations of the current sample - and - hold (CSI - 1). Section closes the chapter with an overview of the evolution of the CSH or SI memory cell (SI MC).Author: Bengt E. Jonsson. A clock feedthrough reduction circuit useful for switched-current systems is proposed. This circuit adopts the concept of current cancellation. It is a signal-dependent clock feedthrough reduction.

1 Introduction + Show details-Hide details p. 1 –8 (8) It has not been the intention of this book to make explicit comparisons throughout with performance achievable with switched-capacitor techniques but rather to identify the state-of-the-art of switched-current techniques. A current-to-frequency converter using switched-current (SI) circuits is proposed. The SI integrator with a hold-and-reset switch can control integration by the output signals. In the proposed circuit the oscillation frequency can be controlled by the input current, and the circuit is operated in the current prideinpill.com: Yukihiro Kuroda, Akira Hyogo, Keitaro Sekine. Chapter Introduction to Switched-Capacitor Circuits For high-speed input signals, it is critical that the NMOS and PMOS switches in Fig. (a) turn off simultaneously so as to avoid ambiguity in the sampled value.

switched-current (SI) circuits. Current-feedthrough in SI circuits is caused by non-ideal characteristics of the Metal Oxide Semiconductor (MOS) switches during the time interval when they are turned off. In this paper, an analysis of the effects of current-feedthrough in SI circuits is given and a current-feedthrough cancellation circuit is presented. • Switched-current circuits implement discrete-time linear systems, using MOS transistors with the gate open as current memory elements.. • The memory elements are coupled by current mirrors. • A clock system with two or more phases allows the connection of these basic elements to form delays, discrete-time integrators and filters. Current sampling techniques Switched-current circuits are typically imple- mented using an S/H similar to that shown in Fig. la [2, 3, 5]. In this S/H, IIN is sampled by Author: David G. Nairn. An alternative bilinear z-transform switched current integrator is disclosed in a paper by I. Song and G. W. Roberts entitled "A fifth order bilinear switched current Chebyshev filter" which was presented at the IEEE International Symposium on Circuits and Systems in and published in the Conference Proceedings at pages to Cited by: 2.
