The ideal block level concept of the current mirror is shown in figure 11.1. Given a current source as the input, the input section of the current mirror looks like a virtual short circuit and reflects (swaps the direction of flow) this current to produce a current sink (the current exitin...
PROBLEM TO BE SOLVED: To improve an access time without being influenced by a capacitance by sensing a current direction of an input signal in response to a sense control signal, amplifying the sensed input signal, shifting a voltage level of the signal which is sense amplified by an input ...
In this paper, the conventional current bleeding architecture which has a high conversion gain and low noise figure is modified by integrating a combination of NMOS-based current bleeding transistor, PMOS-based LO switch, and integrated inductors, thus improving the isolation between the LO and RF ...
Circuit Scenario: I have a current subtractor circuit made up of pmos and nmos wide swing current mirrors. The output of the circuit for now is tied to a...
Due to the integrated body diode in the PMOS switch, a CIN greater than COUT is highly recommended. A COUT greater than CIN can cause VOUT to exceed VIN when the system supply is removed. This could result in current flow through the body diode from VOUT to VIN. 9.2 Typical Application ...
Given a current source as the input, the input section of the current mirror looks like a virtual short circuit and reflects (swaps the direction of flow) this current to produce a current sink (the current exiting the mirror); as a result, we obtain a current sink (figure 11.1a). ...
This basically means that the sum of the VSGs oriented in the clockwise (CW) direction must equal the sum of the VSGs oriented in the counterclockwise (CCW) direction. Due to the current–voltage exponential relation, this implies that the product of CW device currents equals the product of...

(the currents having the same current value of VC/R and the same flow direction). In other words, if the resistance values R of the resistors R112and R122are the same and the resistance values R of the resistors R111and R121are also the same, the drain currents of the PMOS transistors...
