摘要:

AbstractElectrical oscillators are called single‐controlled when their non‐linear elements depend on a unique variable, while they are termed adiabatic when their transient operation signal can be represented as a narrowband‐modulated Fourier series with only a finite number of dominant components, including the DC one. the novel method presented here allows one to analyse the dominant dynamics, steady state and dynamical stability of such oscillators. the approach devised is perturbative and is termed averaging, since it moves from the differential equation in the oscillator signal to provide a set of simultaneous differential equations in the complex envelopes of the dominant components of that variable. Owing to the treatment generality, investigable circuit topologies comprise a linear lumped time‐invariant network of any order with bias sources, and any number of non‐linear elements, with or without memory, with a common control variable. to illustrate the use of the method, formulae concerning a seventh‐order oscillator

摘要:

AbstractA new SPICE‐based approach for steady state circuit analysis is presented which uses SPICE computational capabilities and a master programme to carry out the periodic response. the master programme implements a suitable method for steady state analysis and is linked with SPICE only via I/O SPICE files. This allows the use of all SPICE analyses together with the new one simply by adding a new statement in the input SPICE file. In this paper the bases of this technique, including the chosen steady state method and the whole system structure, are discussed. Simulation results produced by this technique have been compared, by means of two meaningful examples, with those obtained both by SPICE and by a dedicated simulator for steady state analysis working in the frequency domai

摘要:

AbstractA new CMOS current mirror is presented which has the static characteristic of the cascode current mirror and a high‐frequency performance equivalent to or better than that of the simple current mirror. Moreover, the circuit proposed does not present the instability problem of the improved cascode utilized to increase the high‐frequency response.The circuit is designed using CMOS 2 μm technology with various aspect ratios and simulated with the SPICE progr
