Charge-Pump with a Regulated Cascode Circuit for Reducing Current Mismatch in PLLs
The charge-pump circuit is an important component in a phase-locked loop (PLL). The charge-pump converts Up and Down signals from the phase/frequency detector (PFD) into current. A conventional CMOS charge-pump circuit consists of two switched current sources that pump charge into or out of the loop filter according to two logical inputs. The mismatch between the charging current and the discha...
متن کاملLow Noise Amplifier Circuit
By Aalay Kapadia in Electrical Engineering and Electronic Engineering. The circuit topology we used for this project is a cascode LNA with inductive source. Typical parameters are maximum transducer gain, output power , low noise, circuit stability. Here a LNA is designed to obtain an optimum gain with minimum.
متن کاملA High Efficiency and Low Ripple Cross-Coupled Charge Pump Circuit
Abstract: A fully integrated cross-coupled charge pump circuit with four-clock signals and a new method of body bias have been proposed. The new clock scheme eliminates all of the reversion power loss and reduces the ripple voltage. In addition, the largest voltage differences between the terminals of all transistors do not exceed the supply voltage. We have also solved the gate-oxide overstres...
متن کاملA Dual-rail Charge Pump Bias Circuit for Avalanche Photodiodes
In this paper, a dual-rail charge pump bias circuit for avalanche photodiodes is presented. The proposed circuit was fabricated and measured on a printed circuit board (PCB). Experimental measurements show that it is capable of providing up to 50 V bias voltage and delivering more than 40 mW of power for shallow-junction planar APDs that operate between 25 V and 40 V, allowing avalanche current...
متن کاملAdditive Noise Response of a Charge Pump Phase-Locked Loop
The additive noise response of a charge pump phase-locked loop in the synchronous mode of operation has been studied. In order to determine the tracking and noise performances of the loop, mean square values of tracking error and local oscillator phase jitter have been analytically obtained. Analytical results agree well with the simulation results obtained here and elsewhere [3]. The analysis ...
