Switched-capacitor voltage gain elements, in which the gain is precisely controlled by the ratio of two capacitors, are presented. The voltage gain is obtained by means of a transconductance element operating into a switched-capacitor resistor. Circuit configurations use a single operational amplifier or a unity-gain buffer. In some of these configurations, the offset voltage of the operational amplifier or the buffer is not amplified.

A new switched-capacitor integrator with low sensitivity to finite amplifier gain is described. The circuit is simple, requiring very little extra chip area as compared to the uncompensated integrator. It is compared with previously proposed finite gain compensated switched-capacitor integrators.

A simple technique for significantly reducing the effect of the finite gain of amplifiers on the performance of switched-capacitor filters is presented. The effectiveness of this technique has been established by extensive simulation studies. This technique has the potential for simplifying amplifier design and extending the frequency range of switched-capacitor filters by trading gain for bandwidth.

A switched-capacitor second-order building block based on switched-capacitor transconductance is presented. All types of transfer functions, e.g. lowpass, bandpass, highpass, and bandstop are possible and experimental results are presented.

The use of switched capacitors to realise conductances in m.o.s. integrated circuits is well established. The objective here is to describe a technique for realising transconductance elements using switched-capacitors and unity-gain buffers. The application of these elements to the realisation of a gyrator is presented and experimental results are discussed.

A new method for the nodal analysis of networks containing infinite-gain differential operational amplifiers is described. From this description an equivalent network containing only 2-terminal elements and voltage-to-current transducers is derived.

It is shown how the equations of a class of coupled distributed networks can be decoupled, and their transmission parameters expressed in terms of those of an equivalent scalar system.

The letter describes a numerical Laplace-transform inversion based on the Pade rational approximation of exp (z) with any degree of numerator and denominator. User-oriented information is given. The program is intended mainly for time responses of networks with lumped-distributed and active elements where partial-fraction expansions are not feasible.
