A 0.8V, 7uA, rail-to-rail input/output, constant Gm operational amplifier in standard digital 0.18um CMOS

A two-stage amplifier, operational at 0.8V and drawing 7/spl mu/A, has been integrated in a standard digital 0.18/spl mu/m CMOS process. Rail-to-rail operations at the input are enabled by complementary transistor pairs with g/sub m/ control. The efficient rail-to-rail output stage is biased in class AB. The measured DC gain of the amplifier is 75dB, and the unity-gain frequency is 870kHz with a 1

Paradoxical Production Cultures A tale of two films based on Stieg Larsson’s The Girl with the Dragon Tattoo

The objective of this paper is to briefly examine and contrast the two audiovisual productions of Swedish author Stieg Larsson’s first novel The Girl with the Dragon Tattoo from the perspective that the two films were prepared, shot and finalized within vastly dissimilar production economies. The rationale behind the examination is that it seemingly reveals certain paradoxes that appear to challen

Enabling reuse of robot tasks and capabilities by business-related skills grounded in natural language

Definition and reuse of robot instructions is still an art that requires extensive engineering, not only of the infrastructure but also of the adaptation of robot capabilities to the context and domain at hand. Technical approaches are numerous, but the lack of practical success is an indication of hidden difficulties, which we have experienced as complications over the last two decades. Based on

A 1.8 GHz CMOS VCO with reduced phase noise

A 2 V, 6 mA, 15% tuning range, 1.8 GHz VCO implemented in a standard 0.35 μm CMOS process is presented. The phase noise of the VCO has been greatly reduced by means of on-chip filters and one off-chip low frequency inductor. The phase noise measured at 3 MHz offset from the carrier is between -141.5 dBc/Hz and -138.5 dBc/Hz over the whole tuning range

On H-infinity model reduction of MIMO systems

In this paper we study multi-input-multi-output (MIMO) extensions of a recently proposed model reduction algorithm for single-input-multi-output (SIMO) linear time-invariant (LTI) systems. We discuss three versions, including a trivial modification of the SIMO method. Reduced models are found by solving a convex problem with Linear Matrix Inequality (LMI) constraints given a state space model or a
