Provided is an amplifier circuit and method of using the same that features an adjustable resistor network to enable varying the operational characteristics of an amplifier. The resistor network includes primary resistors connected in series with a plurality of adjustment resistors connected to the output of an operational amplifier. A switching network is connected between the resistor network and the input of the operational amplifier. The switching network enables selectively varying the input and feedback resistance of the amplifier circuit to obtain a desired differential gain, while minimizing common-mode gain.

An improved programmable transconductor can be efficiently implemented utilizing a programmable resistor circuit that allows for only a selected portion of the resistor circuit (associated with a desired transconductor gain) to be coupled between summing nodes of the transconductor. Additional switching circuits can be used to reduce gain errors associated with the switches used to implement the aforementioned solution. Additionally, the improved programmable transconductor can be integrated into fully differential programmable analog integrated circuits, thereby enhancing the performance of such integrated circuits.

The inventive level shifting circuit shifts an analog input signal by a precise amount. This allows it to be used in precision instrumentation applications where precise signal shifts are critical. It uses a self-biasing feedback circuit to determine the bias current needed to shift an analog signal by a desired amount. The circuit automatically compensates for influences by temperature, supply voltage, and process variations. This circuit also has value as a stand-alone function for other (non-programmable) products.

An output block for an in-system programmable analog integrated circuit. The output block features an output amplifier that accepts a differential current-mode input signal and provides a single-ended output voltage. The output amplifier is also selectably operable as a linear amplifier, an integrator or a comparator. The output block also includes a common-mode feedback circuit (CMFB), an analog trim circuit (OATRM), a CLAMP circuit, and an offset calibration circuit (CLDAC), all coupled to the differential input of the output amplifier. The CMFB exhibits bandwidth comparable to that of the output amplifier and a drive capability that enables the differential-input to single-ended output conversion. The CLAMP is connected to the differential input in the comparator mode in order to avoid slow recovery from an overdrive condition. The OATRM forces a difference current into the differential input that compensates for a (gain independent) offset voltage that results from various mismatches.
