摘要： This invention is for a transconductance amplifier. The amplifier has an amplifier input and an amplifier output with an amplifier output impedance. An input stage of the amplifier has a first transconductance. An intermediate state is coupled to the amplifier output through positive feedback. The intermediate stage has a second transconductance and an intermediate stage output having an intermediate output impedance. The gain of the amplifier is a function of the first transconductance times the second transconductance times the amplifier output impedance times the intermediate output impedance.

摘要： A temperature compensated piezoresistive transducer includes a silicon body having a major top surface and an under surface. The body has generally parallel spaced first and second elongate slots formed therein extending through said top and under surfaces to define a center portion between said slots and first and second outer portions at the outward edge of the respective slots. The center portion is adapted to receive pressure to be measured. The body has an additional slot extending through the top and bottom surfaces and extending around the first, second and center portions to define the outer periphery of a transducer membrane with portions of the body remaining to integrally support the membrane. Plural piezoresistive elements having elongate and transverse dimensions are formed on the membrane. The elements are arrayed to receive compressive and tensile stress when pressure is applied.

摘要： A self calibrating algorithmic analog-to-digital converter is disclosed for which the gain of the conversion loop is precisely adjusted and controlled by an array of switched capacitors such control being stored in a latch. The offset of the gain stage is reduced by reducing the amount of charge injected from the gate of the input zeroing MOS switch.

摘要： An array of binary weighed capacitors, an additional capacitor having a capacitance value equivalent to that of the least of the binary weighted capacitors, a voltage comparator, switches for interconnecting the capacitors with certain predetermined voltage levels and the comparator, and a sequencing circuit are included. One side of all of the capacitors is connected to one input terminal on the comparator and the other side has applied thereto the signal to be quantized. Switch sequencing combines divided portions of a reference voltage with the signal to be quantized for presentation to the input of the comparator which thereby provides a serial digit output connected to the sequencing circuit. In this fashion, a linear conversion between an analog and a digital signal is made by the sequencing circuit. A nonlinear converter between digital and analog signal presentation is also disclosed.

摘要： A fast parasitic-insensitive continuous-time filter and equalizer integrated circuit that uses an active integrator is described. Circuit techniques for excess-phase cancellation, and for setting the corner-frequency of the filter and equalizer are also described. These techniques result in a filter and equalizer chip with performance independent of process, supply, and temperature without employing phase-lock loops. This 20MHz 6th order Bessel filter and 2nd order equalizer operate from 5V, and generate only 0.24% (-52 dB) of total harmonic distortion when processing 2 Vp-p differential output signals. The device is optimized to limit high-frequency noise and to amplitude equalize the data pulses in hard disk read-channel systems. The device supports data rates of up to 36 Mbps, and is built in a 1.5.mu./4 GHz BiCMOS technology.
