Large scale circuit simulation, such as power delivery network analysis, has become increasingly challenge in the VLSI design verification flow. Power delivery network can be simulated by both SPICE-type circuit-based model and eletromagnetics-based model when full-wave accuracy is desired [7, 8]. In the early time of the time domain finite element simulation [1] for integrated circuit, the mod...

Process, device, and mixed-mode (device/circuit) simulation-based approach is presented for 0.1m gate length CMOS technology optimization and sensitivity analysis. The disposable spacer-based 0.1m NMOS and PMOS transistors with excellent short channel characteristics are designed using process and device simulations. The implant-dose sensitivity of the device parameters around the nominal value...

This paper presents a programmable multi-mode finite impulse response (FIR) filter implemented as switched capacitor (SC) technique in CMOS 0.18 μm technology. Intended application of the described circuit is in analog base-band filtering in GSM/WCDMA systems. The proposed filter features a regular structure that allows for elimination of some parasitic capacitances, thus significantly improvin...

Structural vibration can be reduced by shunting an attached piezoelectric transducer (PZT) with an electrical impedance. Current shunt circuit designs, e.g. a single-mode inductor–resistor network, typically require large inductance values of up to thousands of henries. In practice, discrete inductors are limited in size to around 1 H. By placing an additional capacitance across the terminals o...

OF THE DISSERTATION A Novel Dynamic Power Cutoff Technology (DPCT) for Active Leakage Reduction in Deep Submicron VLSI CMOS Circuits by Baozhen Yu Dissertation Director: Prof. Michael L. Bushnell Due to the exponential increase of subthreshold and gate leakage currents with technology scaling, leakage power is increasingly significant in CMOS circuits as the technology scales down. The leakage ...

This article presents a current-mode quadrature oscillator using current controlled current conveyor transconductance amplifiers (CC-CCTAs) as active elements. The proposed circuit is realized from a lossy integrator and a lossy differentiator. The oscillation condition and oscillation frequency can be electronically controlled via input bias currents. The proposed oscillator can be applied to ...

A detailed analysis of the dc behavior of switched-capacitor common-mode feedback circuit (SC-CMFB) is presented. A mathematical model, useful for analysis, is developed and the expressions for the output common-mode (CM) voltage, with and without considering the charge injection of switches and leakage currents, are derived. Further, the expression for dc CM settling time, is presented. The ef...

Testing of Sequential circuits can be done by two test vectors (all 1’s and all 0’s) if the circuits were based on the conservative logic. The circuit is made to be tested by designing the circuit with the help of Reversible logic gates. Toffoli gate is used as reversible gate in this paper. Sequential circuits such as latches, flip flops are designed with the help of conservative logic reversi...
