High-Resistance Resistor Consisting of a Subthreshold CMOS Differential Pair

High-resistance resistors consisting of subthreshold-operated CMOS circuits ----LSI implementation of 1-1000 mega ohm resistors----

We propose a CMOS circuit that can be used as an equivalent of resistors. This circuit uses a differential pair consisting of diode-connected MOSFETs and operates as a high-resistance resistor when driven in the subthreshold region. Its resistance can be controlled in a range of 1-1000 M by adjusting the driving current for the circuit. The results of the fabrication and measurement of the circ...

On-chip Power Supply for Subthreshold-Operated CMOS LSIs

An on-chip voltage supply regulator for subthreshold-operated CMOS logic LSIs is proposed. The regulator transforms lithium battery voltage 3 V to low supply voltage 0.4-0.5 V for subthreshold-operated CMOS logic LSIs. It monitors the gate delay in the LSI and produces an appropriate supply voltage such that the delay is equal to a value determined by a built-in capacitor-resistor reference. We...

Low-Voltage Chaotic Oscillator With an Approximate Cubic Nonlinearity

A compact eight-transistor grounded nonlinear resistor possessing cubic-like current-voltage characteristics and optimized for low-voltage operation ( 1.5V) is designed in a 2 CMOS process. The resistor is then incorporated into the wellknown Chua’s circuit and tuned to develop the double-scroll chaotic attractor. The inherent nonlinear behaviours of a singleended differential pair and simple c...
