AbstructA novel BiCMOS full-swing circuit technique with superior performance over CMOS down to 1.5 V is proposed. A conventional noncomplementary BiCMOS process is used. The proposed pull-up configuration is based on a capacitively coupled feedback circuit. Several pull-down options were examined and compared, and the results are reported. Several cells were implemented using the novel circuit...

A continuous-time common-mode feedback circuit (CMFB) is presented. A two-stage high-gain architecture is used to minimize the offset of the common-mode voltage. A special compensation scheme enables this circuit to be used in high-impedance current-mode systems without a stability problem. Simulation and testing results show the superior performance of this circuit. It is proven to be an ideal...

We present a feedback circuit that performs nonvolatile correction of instabilities and resonant-gain offsets (&-offsets) in individual cochlear filters. The subthreshold CMOS circuit adapts using analog floating-gate technology. We present experimental data from a working chip that illustrates the performance of the circuit. We discuss how to extend our work to do very long-term gain control i...

Dysfunction of the basal ganglia produces severe deficits in the timing, initiation, and vigor of movement. These diverse impairments suggest a control system gone awry. In engineered systems, feedback is critical for control. By contrast, models of the basal ganglia highlight feedforward circuitry and ignore intrinsic feedback circuits. In this study, we show that feedback via axon collaterals...

We consider the use of feedback loops in the realization of multiple-valued combinational circuits. We show that the number of purely combinational configurations in an r-valued system is llr of the total number. Thus, as the radix increases, the fraction of combinational configurations decreases. We also show that, for every radix value r , there is a circuit with feedback realizing a combinat...

A JFET-based circuit for realizing a precision and linear floating voltage-controlled resistance (VCR) is presented for use in analog multipliers and programmable analog circuits and as a resistance mirror. It uses a matched JFET pair along with an op amp based negative feedback for realizing a precision resistance and a feedback of the source and drain voltages to the gate for realizing a line...

In this paper, we develop and apply some digital design and redesign techniques for ordering the chaotic Chua’s circuit. The idea of using sampled-data feedback for controlling the circuit was previously suggested [Yang & Chua, 1998], which relies on small sampling periods. We show how this sampled-data feedback control method can be significantly improved, so that large sampling times are allo...

We present a silicon implementation of a 4-port universal linear optical circuit. Instead of predefining the exact functionality of a photonic circuit at design time, we demonstrate a simple generic silicon photonic circuit, combined with electronic control and software feedback, that can perform any linear operation between its 4 input and output ports. The circuit consists of a network of the...

Abstract This paper describes the design of Low Noise Amplifier (LNA) circuits with different types of matching circuits at the input side and output side at 6 GHz. This paper compares the results of all possible combinations of ‘T’ and ‘L’ type matching circuits. The designed circuit is simulated with Advanced Design System (ADS) software. Each circuit is simulated for, with and without stabil...
