A circuit and a method for biasing a compound cascode current mirror (CCCM) that enables high-voltage swing at the output and accurate current mirroring is presented. The CCCM has mirror transistors and cascode transistors which may be of a different technology kind. The drain-source voltage ...
In this paper, a power efficient CMOS cascode current mirror configuration with minimum headroom to supply independent biasing is presented. A simple scheme is used to reduce supply voltage, power and the chip area. The cascode current mirror circuit has been implemented in 0.13μm CMOS technology...
Current mirror is an essential component in analog integrated circuit design for biasing and constant current generation. In this paper a design of a wide swing cascode current mirror circuit (WSCCM) is proposed by using Mentor Graphics Design Architect and IC Station which is implemented by using...
而Widlar current mirror的biasing current以对称性为原则来设计如Fig.1(a)所示。 再加一级做cascode可产生更大的输出电阻如Fig.1(b)所示。 Fig.1(a) Fig.1(b) 其中g m13=。 由于整个电路的偏压电流都是由这个偏压网络来产生,故电路中的所有晶体管都会有很stable的g m。 2.Design of the two-stage amp...

node 13. Transistor M106 includes a source that is coupled to node 12, a gate that is coupled to the biasing signal (i.e., bias voltage VBIAS), and a drain that is coupled to node 14. Current source I11 is coupled between node 11 and the low power supply (GND), while current ...
Referring now to FIG. 7, there is illustrated a schematic diagram of a folded triple cascoded chopper stabilized amplifier design that utilizes the biasing method described above with respect to FIG. 5. In the structure of FIG. 7, the switches 46, 48, 50 and 52 are realized with N-channe...
The gate 130A and 130B widths can be different, and if so, this requires a more complex biasing scheme for such a structure, because one FET has a higher IDSS (saturated drain-source current) than the other. FIG. 2 shows two interdigitated FETs 100A and 100B in a conventional ...
