Dynamic translinear circuits and log-domain filters form a promising and challenging
approach to meet the dynamic range limitations that conventional analog implementation …

In this paper the properties of a low-level nonlinear continuous-time circuit element-termed a
Bernoulli Cell (or Operator)-are described in a systematic way. This cell is composed of an …

Log-domain and translinear filters provide a competitive alternative to the challenges of ever
increasing low-voltage, low-power and high frequency demands in the area of continuous …

Design and Analysis of Integrator-Based Log-Domain Filter Circuits deals with the design
and analysis of log-domain filter circuits. It describes several synthesis methods that aid the …

The nonideality studies on biquadratic log-domain filters are extended to cover high-order
filter deviations. It is shown that the log-domain filter nonidealities can be classically …

A transistor-level all npn differential log-domain integrator geared toward low-distortion very
high-frequency (VHF) applications is proposed. Systematic design steps are suggested and …

Log-domain filtering makes explicit use of the diode nature of bipolar transistors to realize
log-domain integrators, resulting in coupled translinear circuits. In this paper, the departure …

An approach to estimate the distortion in log-domain filters is presented. The models used
for the bipolar transistors include the C/sub/spl pi//and C/sub sub/parasitic capacitors, the …

Two variations of a continuous-time instantaneous companding filter were integrated in a 25
GHz bipolar process. Their-3-dB frequencies are tunable in the ranges of 1-30 and 30-100 …

In this paper, the design and measurements of a 1-volt class-AB instantaneous companding
translinear integrator are presented. The use of instantaneous companding and class-AB …
