A general small-signal model for current-programmed switching power stages is used for design-oriented analysis of a 150-W buck regulator and of a 280-W boost regulator. The model, into which the current-programming minor feedback loop is absorbed, exposes the desired tendency towards “constant” output current. The regulator voltage loop remains #he only explicit feedback loop, allowing the reg...

Abstract- A novel low-voltage two-stage operational amplifier employing resistive biasing is presented. This amplifier implements neutralization and correction common mode stability in second stage while employs capacitive dc level shifter and coupling between two stages. The structure reduces the power consumption and increases output voltage swing. The compensation is performed by simple mill...

In this paper, a 0.18-V input three-stage charge pump circuit applying forward body bias is proposed for energy harvesting applications. In the developed charge pump, all the MOSFETs are forward body biased by using the inter-stage/output voltages. By applying the proposed charge pump as the startup in the boost converter, the kick-up input voltage of the boost converter is reduced to 0.18 V. T...

We present the architecture and practical VLSI implementation of a 4-Tb/s single-stage switch. It is based on a combined input-and crosspoint-queued structure with virtual output queuing at the ingress, which has the scalability of input -buffered switches and the performance of output-buf-fered switches. Our system handles the large fabric-internal transmission latency that results from packag...

A current mirror (CM) based on self cascode arrangement, useful for low voltage analog and mixed mode circuit is proposed. The CM uses 4 MOSFETs, has high input and output swing, operating at ± 0.5 V supply. Pspice simulations confirm the high performance of this CM having a bandwidth of 2.1 GHz. Resistive and capacitive compensations result in about threefold bandwidth increase to 6.1 GHz.

This paper deals with RC active biquad working in the so-called current mode (CM). The design approach uses only three transconductors (OTA) with the minimum necessary number of outputs and with only three passive grounded elements. The proposed filter has simple circuit configuration providing all standard transfer functions such as high-pass (HP), band-pass (BP), low-pass (LP), band-reject (B...
