“Current injection has been demonstrated before as a viable means to control SQUIDs12–14 dominated by geometric inductance. These directly-coupled SQUIDs used a large pickup loop to convert an applied magnetic field into a current bias which was injected a smaller, more sensitive readout SQUID. Although the readout SQUIDs in these devices were smaller than the pickup loops, they still used larg...

We present an integrated 2:1 multiplexer and a companion 1:2 demultiplexer in CMOS. Both integrated circuits (ICs) operate up to a bit rate of 40 Gb/s. The 2:1 multiplexer features two in-phase data inputs which are achieved by a master–slave flip-flop and a master–slave–master flip-flop. Current-mode logic is used because of the higher speed compared to static CMOS and the robustness against c...

This work shows the process of characterization and modeling of integrated inductors in CMOS silicon technology for biotelemetry applications [1]. Three planar square inductors with different geometrical characteristics were designed, using the 2 μm CMOS technology of AMS. With physical models [2, 3] and the software ASITIC, was possible to define the geometrical characteristics of the inductor...

This section explains overview of the on-chip inductors. Demand for on-chip inductors has been increasing especially for CMOS RF circuits. An on-chip inductor is a key component because its performance directly affects the circuit performance and the chip cost. The onchip inductors have been used, for example, as a matching network component, as baluns, and as an inductive load. The requirement...

In this article, a nonisolated three-port dc-dc converter with high voltage conversion ratio is proposed. the proposed converter, by changing place of input source between each three ports, different single-input two-output operation modes are achieved. The current ripple eliminated at low side for whole range duty cycles. ratios can be increased increasing turns second winding coupled inductor...

Extensive experimental results for various square spiral inductors on GaAs substrate are presented in this paper. Through detailed studies of the inductances extracted from the de-embedded onchip measured S-parameters, the relationships between the electrical characteristics and the geometrical parameters of the spiral inductors are revealed. Based on the curve fitting technique, a behavioral m...
