Abstract: A logic circuit consists of a first transistor network and a complementary second transistor network connected at a central node. The central node serves as a first logic output. Each of the transistor networks is also connected to a respective root. A third transistor network is connected between an intermediate node of one of the transistor networks and the network's respective root. For a homogeneous graft, the third transistor network has a complementary structure to the transistors between the intermediate node and the central node, is of the same transistor type as the given transistor network, and has inverted inputs relative to the transistors between the intermediate node and the central node. The third transistor network (the graft network) provides a second logic output to the logic circuit.

Abstract: A complementary logic circuit contains a first logic input, a second logic input, a first dedicated logic terminal, a second dedicated logic terminal, a first logic block, and a second logic block. The first logic block consists of a network of p-type transistors for implementing a predetermined logic function. The p-type transistor network has an outer diffusion connection, a first network gate connection, and an inner diffusion connection. The outer diffusion connection of the p-type transistor network is connected to the first dedicated logic terminal, and the first network gate connection of the p-type transistor network is connected to the first logic input. The second logic block consists of a network of n-type transistors which implements a logic function complementary to the logic function implemented by the first logic block. The n-type transistor network has an outer diffusion connection, a first network gate connection, and an inner diffusion connection.

Each of the transistor networks is also connected to a respective root. A third transistor network is connected between an intermediate node of one of the transistor networks and the network's respective root. For a nonhomogeneous graft, the third transistor network has a complementary structure to the transistors between the intermediate node and the central node, is of the opposite transistor type as the given transistor network, and has equivalent inputs relative to the transistors between the intermediate node and the central node.

Abstract: An ion concentration sensor produces a signal reflective of the ion concentration within a solution. The ion concentration sensor is based on an ion sensitive transistor having a solution input, a reference input, a diffusion input, and a diffusion output. The ion sensitive transistor is connected as a pass transistor, such that the diffusion output provides an electrical signal indicating an ion concentration in a solution contacting the solution input.
